If, when eating dinner with friends, you pay for the bill with your credit card and your friends give you cash, don’t do what I do. Don’t think “Wow! $50 extra cash in my wallet!”
NO!!! Put it in the bank!!
I just checked my statement and I have like 5 charges of $50, $64, $25, etc. Then, like in a movie, my mouth agape, I opened my wallet and saw…one $1 bill. Great.
