I can't believe this has gone on for two pages
It is likely that not all delivery drivers are the same wether ASDA or TESCO. They tend to have similar contracts which which rightfully state they can refuse if any chance of personal injury could occur. This kind of statement will be interpreted differently by different drivers, e.g lazy vs diligent.
Due to this type of contract the company has to publicly support the driver even if they are privately involving hot coles and pokers etc?
P.S. You must reaaally know your beans
