Joshua helped me out yesterday and I was having a horrible day, but he was quick to make it so I didn't wait even a second and was very kind and made me smile even though I had been crying moments before. Awesome service and a great atmosphere!

Raven and I had a great conversation together and she is very knowledgeable about a variety of products. I was feeling kind of down when I started my visit and left feeling much happier. A lovely young person and I'm so glad to make her acquaintance.

I visit regularly because it's conveniently close to where I work so I can stop in on break, and it has a great selection of products. But the wait time is awful. I regularly have to wait at the FRONT of the line for AT LEAST 30 minutes because of slow check out times. The staff is friendly, but it seems like there's no sense of urgency to get the line moving any quicker.

I am VERY disappointed in how service has fallen off since they have implemented their new “customer rewards program” in September. I had an order three weeks ago and was overcharged $20 for an ounce. I didn’t have a problem getting a return credit, because I had a screenshot of the sale dates and prices from the banner on the website. Today I had ordered very early this morning before they opened. The items were on sale then; the receipt sent to me reflected the sale price. Yet when I got to the store the price per ounce was inflated by $20. I had 2 one ounce packages so they wanted to overcharge me $40 this time. The manager explained that he wasn’t responsible for any changes in menu prices after I placed my order. I replied that I didn’t expect him to be, but what I did expect was to pay the amount promised to me not even 12 hours earlier, the same day—when I ordered it. They seem to not have the capability to check the price the item was day before; something I think would be easy to do if it benefited them, but clearly it does not. Unfortunately I didn’t have a screenshot of my receipt or the sale banner on the website this time. I’ve been coming here faithfully for 7 years; and never did I feel I had to come in armed with screenshots to anticipate price discrepancies until now. As the manager looked at my phone and saw the receipt indicating the sale prices the morning of; he adjusted my total on that receipt to the higher amount. So, not sure what’s happening here. If you choose to use this dispensary, keep an eye on your wallet. Assume you’ll be charged a higher price, as I was TWICE IN A ROW since their new system was implemented. I can’t help it feel as though they tried to screw me, which is a terrible feeling after so many years of faithful patronage. As I told the young man who argued with me over this and stated, “I can’t help it if the prices change from day to day.”—it WAS NOT the next day; it was the same day, 10 hours later, that I picked up this order and was faced with the “price discrepancies “ about which no one could offer resolution. I won’t be returning after seven years of steady patronage, because I don’t want to feel as though I must proactively defend whatever price I ordered this stuff at. Two overcharges are two too many, but what was REALLY appalling is that the staff were unwilling or unable to help resolve this issue. I don’t want to fight over what price I ordered products at, not when I spend several hundred there monthly and I have the receipt THEY SENT ME to back it up. I’ll find somewhere worthy of my business, preferably one that doesn’t try to inflate prices at the last minute while hoping the customer doesn’t notice. It’s shady, and I’m surprised it’s happened here, as Zen Leaf has always had a reputation for being fair and reasonable.

I wish that most other business were run with the simple efficiency and warmth that Zen Leaf is. Everyone, from the staff at the door to the friendly, knowledgeable staff at the service desks makes you feel welcome. The procedures for purchasing are clear and easy to follow. The atmosphere is fresh, warm, and inviting. You see people from all walks of life here. I’ve had extremely pleasant conversations with staff and patrons, and I have never left feeling disappointed. Shopping at Zen Leaf is a bright, pleasant experience.
