most chain stores won’t allow customers to undertake their own repairs “on the premises” due to previous customer ‘incidents’ which have gotten the H&SE and insurers involved. It happens more than you might think..
sounds stupid? if you want to see stupid, let the public loose with tools, especially sharp ones like screwdrivers!
perfect example comes to mind when I used to work in skate industry:-
13 year old customer at skateboard shop lent a phillips screwdriver and spanner to install skateboard trucks to new skateboard deck sold by shop.
Accidentally stabbed himself in leg with screwdriver, punctured femoral artery, nearly bled to death on premises. Thank god he did not get to cutting the grip tape as the shop had also loaned him a stanley knife to trim the grip tape!
Not the incident any shop really wants or needs.
Most chain stores have strict rules of “no tool loans” and “no tools to be used by customers on premises”
