Rudest cashier ever. My wife, the kids and I went in for a cup of coffee after getting out of the movies. Ordered the same thing I order nearly every day, as that is my neighborhood coffee place and have never had issue until recently, with the same lady behind the counter (glasses, pulled back hair, xmas sweatshirt). After I order, and pull out my phone and state I need to pay with my phone (in which I always pay with there because my chip on the card doesnt work well at all), she exclaims that I need to tell her way before so she can prepare (type the amount in - not exactly difficult to do - its like 5 button pushes). I remind her that I did and that it's actually the barista/cashier's job to remember their repeat customers and she then tells me that "theres no need for attitude and if I don't like it she can ask me to leave".

Shocked by this, all I can think to say is "Are you actually talking to me like this?" She goes on to say that I was being rude to her. I've been going here for over 8 years, and now, dare I say it - Heart or First Cup may very well be getting my business - and anyone that asks if theres coffee nearby from now on, or at least until an apology is made.
