2yo at the laundromat, help??

Title says it all! I have to go to the laundromat today, we are all in desperate need for clean stuff but I’m a SAHM so I would have to bring my 2yo with me. He’s never had to sit there while waiting for laundry to be done so I need ideas to help keep him occupied and happy while I get this laundry done. It’ll take 2 hours at most but more likely to take 1.5 hours. I can’t leave our stuff because people will help themselves to it (yes even if it’s in a machine, people suck) it’s not economical for me to leave our stuff anyway, by the time I got home I’d have 5 mins before I’d have to turn around and go back. So any ideas/suggestions would be so helpful!
