almost had the same experience but it got even worse
i went there me and friend and ordered some food it wasnt too much even and the food came ice cold so a friend of mine asked a waited to heat up the dish which was some chicken wrap and the waiter just told her this is how people eat it and ignored her so the rest of the food came and it was as cold so i asked the waiter to heat all the plates and the guy just told me no i served it and you should eat it it might have been there for a while its not my fault, so i told him you are either saying that i am blind coz i just saw you coming its not that i left and came back i was sitting there the whole time or you are calling me a liar in both cases thats not acceptable and i still wish my plates to be heated, that's when the conversation heated up instead of the plates so he started acting rude, shouting at me so i started shouting back then he kept saying i don't work for you i shouldn't be listening to you as if he is paying for my food or something, then i asked for the manager and his exact words were "go sit down"... he repeated for at least 5 times then i burst at him saying "are you teaching me to behave or what am i supposed to do as you please??? i thought i was the client??!!" then the manager came and even when the manager was there the waiter kept going on in his rude attitude that the manager also shouted at him to go away
even after the manager ordered the waiters to heat up the food the food tasted bad and wasn't that hot, so i decided to let it pass as this was a farewell party and i didn't want to ruin the mood more than it already was ruined
