Unfiltered Story #191597

I work as a barmaid in a large chain of pubs across the UK, taking both food and drink orders at the bar. A semi-regular customer approaches the bar to place a food order. Everything goes well until this exchange:
Customer: last time I was here I ordered a salad and I didn’t get it. *stares blankly at me*
Me: I’m sorry to hear that.
Customer: I want my salad now.
[I know that it won’t be possible for stock purposes to give him this, especially since his claims can’t be validated and the company is very strict on giving away free food but I check with the manager anyway.]
Me: I’m afraid the manager has said that it is not possible as you should have brought it up on the day it happened so it could be dealt with then.
Customer: *talks slowly and angrily* you see, I am a regular here and if I don’t get that salad I will not be returning here.
Me: the manager has said no, so there’s nothing I can do.
Customer: *keeps staring at me like I’m stupid*
Me: …there is literally nothing that I can do.
[He ended up throwing his menu on the floor and walking out. I haven’t seen him since].
