I went to one of my local Starbucks this morning and discovered they had this sign in the lobby. I was happy to see it due to being alerted to this feature when my Starbucks App updated.
When finishing up my day at work, I decided to try out the feature. Ordering an iced white chocolate mocha was easy. I was able to choose size as well as change additions, like pumps of syrup, coffee, type of milk, and whip.
Once I saved my order, I was directed to confirm and pay.
Next was a screen telling me the estimated time my drink would be ready, which was 2 to 6 minutes.
I actually got to counter right as the ice was being added to my drink. The barista realized I had a mobile order and announced I had competed the first mobile Order & Pay transaction at the store. I was asked if I had an issues ordering and how did I like it. To sum it up, I did not have any issues using this feature and really liked it. The time I went to the store was not hectic and not sure if the time of day would affect this feature in any way. Oh and look my name is spelled right.
