Customers Who needs em Oh yes its me .But not for this.

Never had this thought in me head before.But at this time of year im plagued with colds and sniffles repeatedly.Just get over one and get another,every one says Yes theres a lot of it about. Every time we get into a vehicle to test it we have to touch steering switches handbrake seatbelts and everything else on the internal part of the test that somebody could have just sneezed on. Anybody else had this?im getting old but not old enough for the NHS to suggest i get a flu jab. Do they work? Your imput would be most welcome.
