“An ex-girlfriend from years ago would always seem to complain or be somewhat rude to the wait staff even if they were doing a fine job. Kinda bugged me out.”
When a Young Man (which I once was) an Old Guy (which I am now) gave me some very sage advice regarding women: “Watch how they treat store clerks, wait staff, house cleaners, etc. THAT’s how they will treat YOU once they figure they’ve got you.” Could not be more true. Look for kindness, grace, and true class over ANY other attributes, Young Men.
