Ridiculous. There’s enough stuff to be thinking about and getting on with without having to be worrying about getting a “please explain” email because some nosy and uninformed member of the public has decided that we’re not working hard enough.
Those people in the photograph may not even be related to the delays. I don’t know what they were doing there and the busybodies certainly don’t either. It might be that their work has been postponed due to the delays/fire. It’s not uncommon to ring up for a line blockage and be told “it’s chaos up here at the moment, ring back in an hour and we’ll see what we can do.” Right-o, we'll sit in the van, take a chance for some grub and a smoke, and do paperwork if there’s anything that can be done or read up/discuss matters. Might look to a passerby that we’re doing nothing, but it won’t be through want of trying.
