A few friends I know go out for a Christmas meal on the last week of school. Normally I'm not able to go (due to money) so they pop in after for coffee before we collect DCs.
This year they are going to a place I can get my main for £5.
I realised the polite thing to do would be to use my code and still split the bill evenly. But I can't afford this. Would IBU to use my code for my meal and only pay for that, a drink and contribute to the tip?
Friends are aware of my financial situation, the code isn't dependant on their purchase (I could go in alone and still use it) and they could still use another discount of they have one.
