If i see a man walking around in my office with a grey wizard beard and barefoot, I will auto assume it's the senior developer and not a homeless dude.

The really highly paid engineers don't show up to meetings, they call in via zoom from their home.

I used to wear flip flops to the office quite often, back when I went to the office.

Na, it's jandles (thongs/flip flops).

Always a t-shirt and shorts in summer.

CROCS!? Nah, cheap flip flops he bought 6 years ago with the sole practically worn down to solid sheets of plastic.
