In general, I hate when a waiter doesn't believe me, or hassels me, if i ask for food to be spicy. As in, I order buffalo wings...with the hottest sauce on the menu...and I get "are you sure? that's really hot..oooooooookkkkkkk."
But today...TODAY...I went to a new Thai place, craving spicy. Waiter asked me how hot i wanted it, and I said "do your worse...the hottest you can make it." So he brings me a dish, that was repectably spicy but not too bad, and then ten minutes later comes by the table and says "Ok...if you liked that then next time you should order our Thai sauce...it's a sauce that's hotter than our Hot and has little peppers in it, but it bothers some people so I just gave you our hottest normal hot."
