I hope the "princess" wasn't directed at me.
I figure that if alternatives are available, then it's not discrimination. That would imply that any store or office that supplied a service of any sort that wasn't completely accessible (stairs, with no elevator, for instance) was discriminatory. There's lots of restaurants with a few steps up and down, for instance. Lots of retail in older parts of older towns that require walking up a flight of stairs. My yoga studio required the ascent of a dizzyingly steep set of stairs. @Kimmio can tell you that despite best efforts, not everywhere is completely accessible. I just think that, in the interest of public health, in the interest of protecting essential workers as carefully as possible, people who cannot mask should review their hundreds and hundreds of options, from phone order, to on-line order, to curbside pick-up, to delivery, to accessing friends and neighbours, to using a taxi service to do your shopping, if you can't wear a mask, you shouldn't be in a store. I would completely make exemptions, with proper documentation from a GP at least, for medical/dental care. I don't think my dentist would, but if I were in charge of the rules, I would. And if you want a rigid place, our hospital in COVID lockdown is extraordinarily serious about this. A visit to a ward there right now is a nightmare of very careful protocol involving the Health Unit, the scheduling of the visit, etc.
There's a difference between inconvenience (you can't shop in 100% of the places you used to because we're in the middle of a pandemic) and discrimination (you can't acquire this service if you have this condition).
And as I said, it appeared that our store was going for some sort of curbside pick-up/on-line order system, but we've been re-thought or put on the back burner or something. Franchisees don't have huge control over these things, and as the smallest store in the system, probably, a local store at the very edge of a not huge city, we don't get prioritized. For anything.
