I sold a $3500 car once for cash to a guy who sold his goods at a booth 
at fairs and shows. He received lots and lots of $20 bills in payment, 
so that is what he paid me with. I kept the cash instead of depositing 
it in the bank and going to an ATM to get cash out.

One day I was counting out some cash and two of the bills felt funny. 
This was before a lot of the anti-counterfeiting features in current $20 
bills. The bills themselves looked really close to real ones, but the 
feel of the paper was wrong.

Maybe for you. I did a group purchase of tickets for a club I am a 
member of.  Almost everyone paid me for their tickets paid with checks. 
I help organize motorsports events; my expenses are reimbursed with checks.
