I have a pupil whose house I travel to in order to give her her lessons. It's a good 15 minutes drive from my house, but I charge them a bit extra for petrol and don't usually mind too much doing it. However, there have been several occasions when I've turned up and there's been no-one in; I charge them for it anyway, and they've been okay with that. It is a bit of an annoying waste of time, though. And in the past, they have contacted me to arrange another lesson, or occasionally I have rung them. (They have variable schedules, so it's not the same lesson time every week.)
Last time I went, though (about 3 weeks ago now), they weren't there again, and so I left a message on the mum's voicemail saying they should contact me to arrange a lesson. I haven't heard anything since, but don't really feel it's my place to be chasing them - I have enough to do, and don't desparately need the money! I feel like giving it another week, and then writing them a nice but firm letter saying 1) that it's up to them to contact me, and 2) please could they pay my last bill. (There's 60-odd quid outstanding).
I don't have a problem with the pupil, and her parents are nice but just chronically disorganised. I'm not sure if I should say I'm not prepared to teach her any more, as it is beginning to tick me off. (Last time I was going there direct from somewhere else so had been driving half an hour to get to them on time!) I'm slightly worried that if I say I won't teach her, they will get snotty and refuse to pay my bill. But I don't really want to go crawling either to fix up more lessons, if they are going to mess me about.
