Yesterday a friend of mine had forgotten her purse and obviously as it was belting hot I was concerned about her dehydrating so I offered her to get herself a drink using my card (I'd just been in for one before she met up with us) she gratefully accepted. Later I saw it was a couple of quid she'd spent. Not great amounts but baring in mind my drink had cost me around 50p I was surprised (it was one of the discount shops). My other friend happened to mention she hasn't just bought a drink. I was frustrated as she didn't even offer to reimburse me so I messaged her and politely asked if she could send me over the money. She did, but didn't reply to me so I assume she's annoyed with me.
I'm not particularly well off which she knows but if it was just a cheap drink I would have told her not to worry if she'd offered me the money. Anyway now I'm thinking I wbu in asking for it?
