Attended a 6pm wedding at a church (which used to be considered formal) and a friend of the groom came in with shorts and flipflops. I leaned up to the ladies in front of me who I knew and said....”My mom would’ve slapped me three ways to Sunday if I came to wedding dressed like that.” They all laughed. They know my mom. ;)
Don’t get me wrong. I get that some people can’t afford ‘Sunday Best’. Have a friend who can only afford overalls. But when he attends church functions....he puts a jacket on over them. And those overalls are PRESSED with creases. I kid you not. One of my fave people on this planet.
Your friend sounds like a gent. Flip-flop man should be slapped around the earhole.
