Feel free to have your own private firefighters doing other things when they get the call to come for the fire which they clearly will not be able to go to until they have finished whatever it is they are doing.You can put a price on anything.
IMO we should pay firefighters only when they actually fight a fire and not the 99% of the rest of the time
Meanwhile the rest of us will stick with what works for the job, for putting out fires as quickly as possible and saving lives. Whatever turns you on.
