We have a mobile hairdresser who comes to our house every six weeks. Longstanding arrangement, has been for years.
Usually we get our hair done on a Friday but we had to switch the day for this visit. I have stupidly got mixed up - I thought it was tomorrow but it was today. Only realised when she was on her way - cue massive panic as we weren't in. I sent the payment immediately and apologised profusely. It was absolutely my error.
She has said she can fit us in an evening next week. We never cancel, don't worry, we will make it work was her response.
Would you expect to pay again? Obviously this is reasonable given she had zero notice tonight, so I'm fully prepared to write off tonight's money. But I actually can't afford to pay twice, so I need a sense check of whether or not the general assumption would be that I've already paid and am cashing it in next week, or I need to say we can't do next week and just leave it.
I don't want to ask in case it is really obvious and I look presumptuous and/or make her feel bad for asking for the money twice.
YABU - of course she'd charge twice, you need to make it clear she shouldn't come next week
YANBU - she is obviously rescheduling which is very kind of her, tip her generously but no assumption of paying twice.
