Sounds like one of these cases where they have just cobbled together their T&Cs from different stuff they have nicked elsewhere and I expect no-one is paying attention.
I mean, if they are supplying wooden tables - that breaks their system immediately. I don't know there IS a way to really flameproof wood, is there?
Surely they'd need to be supplying metal tables.
Probably just a butt covering thing. You could always get the spray and show willing though
