NO paper drink cups in my jeep, I told my wife the only thing she is allowed is a double walled closed top coffee cup.
Not putting up with condensation from a cup.....she complained at first, so I asked her if I could use her Baby Grand piano to sit my cold can of ale on.
She went out and bought a double walled closed top coffee cup.....
Problem solved.
I don't use paper cups. I get iced drinks that come in plastic cups. Well for now they do. LOL Pretty soon those will be banned too.
