Yesterday I went on a field trip with my school to a place that had a bunch of bouncy, inflatable slides and castles (the kind with a fan continuously blowing air inside).
All the items had warnings on them in English about not exceeding the weight limits. Even the school encouraged me to ignore them. The staffs certainly didn’t seem to understand the warnings about things not to do, since there were other instances of people violating them.
The kids at school liked it when I made waves by bouncing up and down. I thought it was most fun to shake from side to side to simulate earthquakes inside the bouncy castles, the kids liked it too, but the staffs did take exception to that behaviour.
