Give them something like this but BTC instead?

Politics is a bad Idea to bring up, rather tip them in satoshis.
Just ask if they take a tip in sats.
Won't work well in america where tips make up half the salary.
Coincidental a coworker gifted me a Bitcoin Pin today and it's beautiful.
Should become a trend to wear one so others know they take tips in sat
Yes, removing the political position and just leaving the gift fact would make this better. And incentivizing BTC would help.
Maybe leaving a QR code or way to request sats to get more of said gift?
