Mine is people using are instead of our. I hear this all the time from social media, news reporters, and I see in in writing. Instead of our, they use are as if they forgot the word our exists.
That every store wants you to sign up and have you give them your details.
When I bought a shirt in a department store a couple of years ago and the guy wanted me to give him my email address “to save paper” (yeah right), rather than give me a receipt. It was like we were having a stand off for a while there. I just want to buy a shirt not sign up for ongoing spam!
My favorite thing to do is I have a secondary domain name that is setup with a catch all email address mailbox. So when they ask for a email i just give them nameofstoresux@domain.com and when they say i need a real email address I say it's real. The look on their face when my phone buzzes with the recept is priceless. Then promptly back hole that address
I don't even bother going that far. I just have a [words]receipts@[domain].com and use it for all of those e-receipts, accounts that make you sign up at checkout, known spam generators.
If I need to search for a receipt for any reason, I have it there. But none of it clogs up my real email
