I would be tempted to drop those with awkward parking, but one set of 4 properties together amounts to £68 per month, plus it's part of a bigger contract worth about £359 per month. Also, aside the parking problem this is easy, well priced work (£50 per hour, per person)
I'm worried that if I stopped the awkward ones I'd lose the whole contract. Going early doesn't help, still no parking. No chance of just parking illegally since doing so would block a main road.
I think I'm going to have to get a trolley, much as I hate to admit it. I'll have to drop it off, go and park the van in a pay-and-display, and walk back. What a pain, but at least I might be able to stop working on a Sunday, so that's something.
