I may be socially awkward/ignorant here, but is it normal for coworkers, who work with one another every single day, to shake hands to say hi/bye at company events?
To give one instance, a group of coworkers and I went to a gathering and about five minutes later, another group came, and they shook hands saying "hi" (even though we'd JUST MET like 10 minutes before at office).
I didn't offer my hand because I didn't think it was expected until I saw everyone else was doing it, which I found a bit weird. It's not like we shake hands to say hi/bye in the office everyday.
What do you think?
