I Don’t Work Here, Does Not Work Here, Part 27

(I am shopping on my lunch at a retail park near work. I am talking to my mum on the phone as I walk around the store. My workplace has casual dress, so I’m not even wearing anything close to a uniform. As I’m talking to her about cookers, this happens:)

Customer: “Excuse me, young lady! It’s extremely rude and unprofessional to be talking on your phone during your shift.”

Me: “Err, I’ll call you back, Mum…”

Customer: “That’s better. Now, tell me where the toasters are. Honestly, so rude!”

Me: *scowling* “I don’t work here. What on earth made you think I do?”

Customer: “Well, you’re the only other person here, of course.”
