Big Bob's Restaurant & Pizzeria Inc

Good food but puzzled over the 15 percent added on bill for tip. They said that it was visa and not them and since I left tip on table it will come off my card in 5 -7 days. Don't understand why visa picked this one little restaurant above all the restaurants to do this. I am new to the area and a widowed senior and eat all my meals in restaurants.Like I said Good food but pay with cash. 05/2012
