A friend and I meet weekly for walks and take turns to pay for our coffee and pastries. Hers are always a lot more expensive than mine and sometimes i bring my own hot drink so am paying for my pastry and her coffee and pastry too. Prices have gone up and it does add up over the month. I've found I'm turning down walks at times because of this and making excuses not to meet. I'm thinking of saying at the next walk, 'do you mind if we pay for our own, because I am watching my budget?' or is there a better way to word this?
