As Finals said, when severe turb kicks in you really don't have time to do a lot, let alone try to get back to the galley. Our girls/guys are told to do exactly the same, wedge the trolleys in against seats and try to sit on empty seats or indeed the floor. If they've got a full kettle and cant do anything with it then they're told to tip it on the carpet.
So in short, yes our crew would have done the same.
