Highly likely. I once worked in an office where the contract cleaners had a check list to follow when cleaning the toilets. This was religiously followed, but there was one problem....
The list did not include cleaning the floor! So over time a distinct stripe appeared on the floor where feet went compared to the areas where you don't put your feet.
A bit comical really, but a good example of the dangers of people slavishly doing a task and doing a job
