Fully prepared to be told iabu but I've just had an engineer out to repair my washing machine and he wanted a few big towels to mop up when he opened up the filter. I only have four bath towels and I don't really want my good towels manky from mopping up the floor (my floor is clean but all the water leaking from under the kickboards is filthy), especially if he couldn't fix the machine. Most of my hand towels were sodden from the initial leak that he was out to fix. Why do they not have their own stuff to mop up? This has happened loads of times when I've had plumbers and engineers out to fix plumbing things. Painters carry dust sheets, why don't plumbers have towels? You know you're likely to be dealing with puddles of water so surely you come prepared?
