I disagree. Hardest I’ve ever seen to not tip is click “other amount”, press 0, you’re done.
Your argument about a livable wage would have made sense years ago when there was a separate wage for tipped workers. Everyone in Canada get paid at least minimum wage now.
While wearing a mask is never a bad idea, it is absolutely not necessary to not get sick. I am also immunocompromised and I have stopped wearing a mask. I wash my hands very often and never eat handheld food without washing first. Zero issues since getting covid back when I was wearing a mask religiously.
