Would it be worth it to pay a someone to appear to donate every time a crowd walks by?

I love seeing live performers although it depends on the situation. In Paris the hallways are too small and the buskers are basically blocking the already crowded hallways. In NYC the ones that actually come on the trains and then go around with a hat make me feel uncomfortable although any performer who's really good I appreciate.

I'd also be curious how those numbers change in countries with larger coins. I assume it's easier to give coins? No worries about bills being blown away. Coins "feel" more disposable? There are €2 coins in Europe. There are 500yen coins in Japan (about $5) where as there are only basically 25 cent coins in the USA (yea 50 cent and $1 coins exist but are not common)
