Yes, YABU.
Live in Scotland, work retail. Won't say which as outing, but not vital goods like groceries. We usually shut at 8pm, (although often aren't leaving until 8.30pm or after), except for 6pm on a Sunday - which is nice when you're the one shutting up shop.
Still, I have people rattling my locked doors at 6pm on a Sunday, or coming in at 3 minutes to close expecting a service that takes us past closing - complaining and expecting my staff to stay late when they want to enjoy what's left of their evening (and unpaid, because the company has set hours allocated!)
I like retail, and I adore customers. But it has to be said, those fuckers rile me. Because at the end of the day, we are open 11 hours every single weekday, and 8 hours on a Sunday. Why on earth can people not manage any of the other 70+ hours over the course of a week?
And don't get me started on 'I work X amount of hours per week so it's hard' - yes, I'm well aware, because I'm one of the retail workers stuck working until most of the other shops close at 8pm, too! I still manage to do my shopping..
And yes, worked retail in England where I was born, and the 4pm close on a Sunday was absolute bliss.
Everyone wants everything available to them, all the time - that's the problem. Even GP practices don't open on a weekend at all, for goodness sake. Nothing is that vital shopping-wise.
