I ordered a BMT. Upon checkout/paying, the women asked if I wanted my receipt, I replied, yes. When I looked at it, she added a $2.89 tip. I called her back and questioned it. She appeared yo be very nervous, and apologized. She voided our that ticket, and recharged without the tip. After that, I won't be going back. Adding a tip is not an accident, thats drliberate.
