The absolute WORST perve of mine these days, are the Starbucks-type baristas! This particular issue started off as a local millennial/ snowflake coffee snob thing, but the corporate morons are propagating this globally to other stores, employees, customers, and other retail outlets: "For yuh"
Examples (that make me want to hug a chainsaw everytime that I hear them):
Ordering a coffee, they will reply: "What else for yuh?"
I'll answer nothing, they will say: "That'll be $3 for yuh"
Often, I will ask them if that is a Starbucks thing or just bad English. The common response is that they never thought about it, and that I'm right- it sounds terrible and ridiculous. When I'm in a bad mood or sense they are hostile, I'll ask them to "hold the yuh" after I state my order (which opens the door for me to point out the horrible grammar).
