mumochange 

When your mother has to use the exact correct change whilst paying for goods which she thinks seems to make life easier, but actually makes everyone's life more difficult.

check out girl: " that will be £9.76 please"
Mother: "OK, hang on, I have the correct change" *five mins later* pays
Daughter/son : " you're such a mumochange "
