Retail things

Retail things So I work a retail job as a tasker/freight, so I don’t need to really talk to as many customers as other positions and I love it. I’m better with more “spontaneous” conversation, so the only time I have to interact with customers is if they ask me a question. My manager told me they want me to train on register, mainly for Black Friday and I’m crushed. I understand the demand, but I would have to ask EVERY SINGLE CUSTOMER if they wanna sign up for rewards, credit cards, etc. and I struggle with ALL of those sounds/consonants. Not to mention the amount of sign ups you get is tracked so there’s pressure to get customers to sign up. I am gonna have a conversation with her later about it but I just needed to get this out.
