how do you get tips besides asking, having a jar, or putting up a sign?

The only other way is to hope... do a trick that requires a borrowed bill and hope they decide to give it to ya afterwards.

If you don't mind getting small change, get the 3 in 1 quarter. Some people will let you keep it. StreetMan.

Oh crap, I swallowed half your coin, see yea.

I personally don't work for tips. If you get them, great. But the more you think and work for those tips, the more it takes away from your performance.

But that's just my opinion.

Do pen thru dollar, and say you will show them one more time if you can keep the money. I put up a sign at my ofifcial shows that says "1,000,000's my lucky number, but any tips would be appreciated
