I feel that if I put all coins in my jeans pocket, they will make the pocket dirty. Also, every time I go home I need to empty all coins out of the pocket. Then I need to put them back in when I go out.
yeah, it's not convinient to not be able to carry coins in the wallet. But even more inconvinient to have a big wallet....
So coins go in the car for me and wallet just hold cards and bills. I try to use the coins all at one go when I know I'll be buying stuff that's gonna be a cent here and a penny here, etc.
