When I lived in London, I was real poor. I worked at a hostel, but I didn't have a visa and I could only work for my accommodation. I had absolutely no spending money. So when I was bartending at the hostel, I would convince guests to bring me food. They always did. I can be quite persuasive. People would bring me doner kebabs, pizza, fish and chips, McDonalds... pshh, some of them would even go straight into the kitchen and start cooking for me. It was fantastic.
If a guy was into me, he’d bring back a little something extra, like a bottle wine, some liquor, or a classy case of Carlsberg. I’d hide it in the bar fridge and we’d drink for cheap all night. The hostel would lose money, but I sure got off well.
(And don’t feel bad for the hostel. They overcharged people and then offered essentially no amenities. The place was a joke.)
