... the expression "invitation to treat" and am not sure how it figures. As for the supervisor, it was a case of wouldn't, rather than couldn't.

All this probably makes me sound like some irritating and sanctimonious git. I'm not (well, unless you ask my wife) but I'm just sick of having to take sub-standard service from organisations that rake it in and treat the customer as a semi-irrelevance. They get my goodwill when I spend my money there, so they can show the same by sticking to an advertised price, whether they're compelled to by law or not.
