From a cruise ship hotel manager. This is not me.
I have managed Hotels on cruise ships for nearly 30 years; 28 different ships for 18 different cruise lines.
I have had 10s of thousands of tipped crew working for me over the years.
Every few months we get some guest who thinks it’s cute to tip with strange currencies or denominations.
The crew brings the odd bills and coins to me to see if I can change them for something that’s is useful to them. They cannot take the strange currencies home, as they cannot change them there. Many times they cannot find time or a location to change them during the cruise. Generally the crew purser will not accept any unusual coins or bills from the crew. So the crew is usually just stuck with them.
After smiling at you when you hand them the strange bank note, they only remember the nitwit who thought he / she was being cute.
$2 bills are a total challenge for a crew member to use.
