I try hard to relate to people sincerely and as a fellow human being, and not walk over that line between employee and customer. I totally understand that the person is just doing their job, and maybe just doesn't want any more interaction than absolutely necessary. I like to tell quick dadjokes, at the very least, and I feel bad about kind of pressing one on someone who clearly did not want to be a part of my hijinks the other day. I did get a little smirk back, so it wasn't all bad, but still.

On the other hand, for example, another recent shopping trip put me in a cashier line behind someone who was obviously being somewhat difficult to a clearly young cashier. After they cleared out, and after my transaction was complete, I made a point of saying to the young man, "You're doing an excellent job, really. I felt you might have needed to hear that." I wasn't lying, he was being focused and patient, although some of his nervousness was still showing through. He thanked me, and said it was his first day solo on the register. "Well, you're doing great," and I departed.

I have many more experiences like the latter than the former, so I think my approach is doing good overall.

In your example, I'm the employee. In actuality, I am the customer. And I try to interact with everyone on a "we're both people with lives and hopes and dreams" sort of basis, not in the banal "weather chat" kind of way.

Bruh, why are you on literally every thread telling people there's no value in going to the cashier? What skin in this game do you have? Are you a grocery store franchisee?

So the only “social interaction” a grocery store check-out employee should have are the negative, abusive ones? If I chat pleasantly with a checkout person, I am interfering with your life? Hmmmm……

Oh I forgot this was /canada - I'm in Illinois, outside Chicago. Cheap plastic shopping bags as far as the eye can see.
