There is a shawarma place near my work that advertises that it has baked potatoes. Also on the menu are falafel and, of course, shawarma. I am a vegetarian and had a huge craving for a baked potato once, so I went there. The guy tells me they're out of baked potatoes. So I ask for falafel. Nope, they're out of falafel, too. Oh well.
The second time I go there I get my falafel and it's great.
The third time I go and the guy who runs the shop is talking on his cell phone. A lot of shop owners do this around here, and will often put the customer on hold in favor of their phone call. I order falafel, but of course, they're out of falafel again, so I just order a pita with hummus. The guy starts preparing the pita with his bare hands, not washing them first, and continues talking on the phone and doing the mouthing/pointing thing to me so I can tell him what I want in my pita instead of actually talking to me throughout the entire transaction. At one point he scratched his ear and then continued to prepare the food with his bare hands. He never said a word to me other than mouthing the bare essentials to me throughout the conversation. I was really grossed out and will never go back there again. Not to mention the odds of them actually having something I want to eat if I go back the next time are slim.
