I don't either and I'm taken aback by all the gold digger comments. I wouldn't want my daughter to date some loser who can't pay his bills and whose bad credit will become her bad credit if they plan a future together. When everyone has a Credit Karma app on their phones, asking what their credit score is is a simple no-brainer.
No different really than wanting to know someone's criminal background check or how many illegitimate children they're paying child support for.
