I'm a little late posting this but figured it was better late than never: the following happened a few months ago at the Tempe location.
Let me start off by saying I really, really like the food and they have a great selection of beer. The problem was with a waitress (she's blonde and thin) and how she treated me during our last and final visit to this restaurant. During our meal, I asked for a recommendation for a beer and gave her characteristics of beer I like as well as a recommendation for a pasty (I am really not picky but I cannot handle a lot of spice). I ordered both things she recommended and both turned out to be really not what I wanted at all. She recommended a beer that was really hoppy (when I had told her I like pilsners) and a spicy indian pasty that had a lot of curry (I'm sure it would be great for people who can handle spicy food--just a reminder that my issue with this restaurant is not with the food). During our meal she was really inattentive and it took around 30 minutes to get our check after we had asked for it. Because my boyfriend owed me money from earlier that day, I tipped lower (around 12%) and he tipped higher (around 30%) so our average tip on our meal was OVER 20%. We decided to leave a good tip because, despite the poor service, he really enjoyed his meal and we have had good experiences there before.
This is where things get really, really bad.
After leaving, I realized I left something on our table and approached our waitress and she gave it to me. After I thanked her, she said "thanks for the (expletive) bad tip." I could not believe that she cursed at me for a tip that was over 20% and I was completely dumbfounded. I tried to find the manager but was unable to. It's a real shame that she ruined my experience with Cornish Pasty. All of my friends I was with as well as others have vowed to not go back there.
