would also be nice if mod can tell us where the delete button is… 
anyway i always used a gas cooker, as did many drivers and some still do. Back in the day when we had trailer boxes, my cooker was in there , a tad cold sometimes when standing outside, but never any issues…why even many EE drivers cook outside, albeit with a cardboard box suitably placed to stop wind from blowing it out…microwaves wasnt invented back in the day and nor electric kettles, and air con…to name a few…but all it takes is common sense…and nothing to do with whether a company takes a drivers safety seriously or not, more about protecting their equipment, If a company does not allow cooking stoves in the cab…then its their duty to supply whats needed…or double the night out money to enable drivers to eat in restaurants/cafes.
