As I am on gap year and have not been doing anything. I got depressed of all the free time so thought that I'd work part time. So, I got a job at a Chinese takeaway and have been working here for a week now. Anyway, a customer called at the Chinese takeaway. Everything was fine at first, I was being so nice and giving good customer service. He said that he wanted 'pancake rolls'. And, I said that we don't do them. So, all of a sudden he became rude. He's like 'I ordered like two weeks ago twice, and at that time, I got the rolls'. I gave the phone to my colleague, who has been working here longer. He explained to him saying that we only do three rolls: chicken, veg and duck but no pancake. So, he asked for chicken. So, my colleague said that 'now, I'm going to pass the phone back'. So, when I got the phone back, I apologised and said that 'sorry, I didn't understand, you asked for pancake roll and we don't do them, Sir'. He said 'no, I'm sure it is my fault, as I'm English, right? Stupid'. Then I said 'ok, Sir'. So, he's like 'don't call me Sir, I'm a working class person like you, so don't call me Sir'. I passed the phone back to my colleague because I can't deal with such rude ass people. He literally made me cry. I think I shouldn't be working. Why are people so mean? He called me stupid and was racist.
