I already sent back a dish 4 times once, but that was a bad case of "I'm not cooking your pasta right". Maybe the chef was mad that day. The food was cold, so I asked them to reheat it, when it came back, some of the pasta was stuck solidly together and felt undercooked, so I sent it back again. The third time, I realized there was no chicken in my chicken alfredo and lastly, I sent it back because there was little to no sauce left on the dish. In the end, I just told them my appetite was gone (blame it on the bread sticks on the table... grrr).

I also resend a sandwich from a restaurant 3 times because the person gave me the wrong sandwich 3 times, lol.
