What an odd thing to ask. Why wouldn't they be?
Not sure how likely that will be (the bars where factory workers hang out tend to not be the ones in tourist areas, for one), but it seems plausible to me.
I wouldn't let that stop me from travelling though.
Americans pretending to be canadians while abroad to be treated better was already a thing before this happened.
Your reaction of ignoring this problem and acting as if all is normal because it doesn't affect you amplifies the problem.
There is a problem; it has existed for a long time and it's called complacency and stagnation.
