Once upon a time I got a job working at a swimming pool supply store. For a total of about 15 min during my very first shift I was in the main room putting price stickers on things and whatnot. For the remaining hours of my shift I was back in the chlorine room filling up chlorine tanks. Tbf the pool store was following regulations as far as I know. I had goggles and gloves and the room had a big ventilation fan and all that. But even still, I got chlorine all over my skin and clothes and was perpetually dehydrated from the fumes. Had to run to the water fountain like a million times. Afterwards I decided there was no way I was going to work with chlorine all day every day until it killed me so the next day I came in and asked the manager if there was any way I could do other work and not be in the chlorine room. He was like, “unfortunately that’s the job”. So I told him, “ok I understand. In that case I don’t think this is going to work out. Thanks for the opportunity though!” And I left after only one shift. Shortest job I ever had.
