Sorry to be so dense, but I am really confused as to how you know the woman with the gasoline pump is a lesbian. Help me, O, Enlightened One, I want to learn.
If a female gets the 'dyke doo' before she hits fifty, and she's not super model pretty, she's a lesbian.
Add in the comfortable shoes and the fact that she's pumping her own gas.
LEZBO.
Class dismissed.
