Seize The Pettiness

I have non epileptic seizures. Depending on how bad they are, I will sometimes keep working after a seizure if I feel well enough. 

I work in a retail chain in a small village. One day, I had just had a seizure and was still feeling a bit shaky but well enough to work, so I went up to the cash register and served this lady. When I had scanned all her items, she spoke up in a rude tone and said (I am paraphrasing as this event was a while ago):

Customer: “You know, you really should offer people a bag before scanning, it would be much quicker that way.”

Me: “I’m very sorry, I’m just having one of those days.”

Customer: *Rudely snapping back.* “Well, I’ve had a really bad day, so that’s no excuse!”

I was taken aback, but decided to be petty; I changed my tone to sound extra apologetic.

Me: “You’re so right. I’m so sorry, I just had a seizure, so I’m a bit wobbly, but you’re so right. I will definitely do better next time.”

Customer: *Shocked.* “I didn’t realise. I’m so sorry.”

But I doubled down.

Me: “Oh no, you were right. I should have done better; I am so sorry.”

She quietly paid, muttering a sorry as she left.
