Yes - exactly like those Teams messages, but at least in a company, there are somewhat relationships and expectations to help each other. But I hate the ones who only contact when they want something, and it is never anything good :D
I ... am not going to engage. If I was going to give, I would have done it already.
I hate being stopped like that. It is an attempt to guilt you into giving - I give already, thank you. There are many ways to give without doing it on the street with someone waving a can.
And at least in a company, you are normally getting paid to become increasingly infuriated at vague suggestions at tasks that should be added to your list, but are really someone else's job entirely.
