I fucking hate false courtesy.
Just help me and don't be a dick.
I despise it when anyone says anything close to "thanks for choosing ____!" Or "Thank you for your business!" at any sort of chain or multimillion dollar company.
We all know it's fake, none of those employees actually give a fuck. It's demeaning to your employees to demand false cheer like that and I dislike the company more when ever it happens.
I would prefer a helpful rude employee than a useless sycophantic employee.
My grandpa was super healthy up until 86 or or so. Every day oatmeal and a hard boiled egg. Little bit of cinnamon mixed with milk.
