I don't mean having to be careful because you're short of money - I'm from a background of my parents not having enough money to pay all the bills. I don't mean looking for a bargain - we all do that
I know someone who hangs around the supermarkets when they're reducing the food that's past it's use by date and buys as much as she can carry. Buys nearly all her clothes from charity shops despite having their own business and renting out several properties.
I had a boyfriend I lived with who if my family or friends came to stay he bought his own food and refused to contribute anything financially to extra food or drink for them even though I did for his friends and family - I left him after he did this with my mum
Those that will always buy their own drink rather than joining a kitty
A friend who overpaid me for tickets by £2 and sent me a text saying could I transfer it into her bank account ASAP, like now, again she's by no means hard up.
One who complains that her cheap kitchen is looking tired and chipped after 5 years - and mocked us for getting a more expensive good quality one
Another one who's always telling me I could have got an item of clothing I'm wearing cheaper elsewhere - so what? I chose to spend my money how I want
