Even inside Pando's offices, people offer a hand without thinking (or did before we switched to remote-first). And it is indeed awkward, but we've taken to making it less so by "taking on" the awkwardness - "Oh, gosh! We're not meant to do that anymore are we?". When I've had visitors to the office I explicitly warned them in advance about the lack of handshake in the directions email (and also point out hand-washing facilities). However, foot bumps and elbow knocks annoy me more than the lack of handshake. They both look daft and I can't imagine a foot bump being trivial if you're even slightly infirm. I'll stick with the Vulcan salute, thanks.
