It can be worse, because when I used to test I followed the instructions on the kit.They do it right in front of you, I cant imagine it would be worse.
I have seen shop staff who ignore things like "shake well and wait 30 seconds before adding reagent 'B' "
Just chucking it in seems OK to some of them.
And I'm sure there's a reason you're supposed to measure out (eg) 5ml of water and not just put 'some water' in the vial.
Of course some shops are great, but some are very dodgy.
