At the Launderette, there are 4 washers in total; 2x 20kg and 2x 9kg plus two massive dryers. When I arrived all the machines were empty, I put my washing in a 20kg machine and started the cycle.
A couple minutes later two guys arrived with an enormous amount of washing in shopping carts - they filled the rest of the machines and still had enough for several loads more. A minute later another person arrived and realising all the machines were in use sat down to wait.
My washing finished first and as I switched it over to the dryer the lady who had been waiting went to start loading her washing into the now empty machine. But the two guys said they had dibs on the machine as they weren’t done with their washing and were there first!
What’s the etiquette here? If you have multiple loads of washing do you get to use all the machines simultaneously or should you use one or maybe two machines (accepting you’ll be at the launderette longer) and leave some machines free for other customers?
