The "Meh. I've experienced better." that pops up after giving this place two stars could not have been a better choice of words to describe the service here.
I do understand that they may get busy during the day but when it slows down to one person every 5 minutes (as it was with my visit) then take the time to relax and speak with your customers. I don't think the coffee is the best in the world; I have had better. So in my opinion, in order to keep people coming to your store, you should have excellent customer service skills. My order was taken, name taken, money accepted and then I moved right along.
Next time, I will find another location. If there is not one to be found then I would rather purchase coffee from the gas station.
