I`m meaning height,I do think this may be the case,less cancellations or "not this times" as their sheer size can subconsciously intimidate the poor householder.
Whilst tradding then hundreds if not thousands of times a year they dont need any reach assistance for ground floor windows.
When using wfp then the angles are always more favourable such as clearing the edge of the flat roof etc. Also if they have bulk with the height as well then lifting anything heavy is mathematically much easier as a proportion of bodyweight.
I`m strong enough though at 5 foot 8 1/2 but i think i`ll look out for some boots with 6 inch heels.
I`m not entirely jesting,if i ever employ, then with these facts in mind, i have to be biased towards the big bloke.
I reckon there will be more "big blokes" posting on here as they have enough energy left to think due to the working day being easier than the one`s encountered by dwarves.
So that has sealed it,the big guy gets the job as he is likely to have a bit left in the locker allowing him to think whilst working.
