Funny half related story. For a bit in my mid-20s I was a manager in training for enterprise (shit company, shit job, do not recommend). I’m this position, we were required to wear a suit, even while cleaning the cars. One day a dude came off the plane looking for a car, I was helping him and giving my speil and he pretty politely stopped me and said something to the effect of, that’s nice and all, but I don’t really trust dudes in suits. A little caught off guard, but attempting to be friendly, I said cool and let him do his thing. It still sticks with me. Something about a suit can say, I‘ve decided to look presentable so you believe me. Not sure if it’s a positive or negative, but he‘s had me thinking for ten years.
At one of my first jobs, they had a policy that you couldn't meet clients without a suit and (company) necktie. Since we mostly accompanied the sales department to sit there and shut up unless specifically asked a technically question, we took to calling it the "liesuit". After all, it's what you wore when lying to your customers.
