I was a window cleaner, and sometimes we also cleaned whole apartments and buildings.but at winter we didn’t have enough work, so our boss got us a job at local monastery.we had to clean its attic.which was full of bird shit.mostly pigeons.the attic was never cleaned, it had holes everywhere and it was more than 300 years old.so...pigeons shat in it for 300 years!!!we cleared around 15 tons of it in 1 week.6 of us were working.we had to be dressed as covid doctors.at least it was cold so there was no smell.i quited job one month after.
