On a more serious note we have a memo stating company will support if refused toilet/hygiene facilities…
Can say that defaccacating (that’s pooing for us lot) on the yard is not the right way forward. Simply refuse to tip due to unsatisfactory hygiene and leave site.
Office bods will pick up the slack, take photos if poss.
Not sure what photos will suffice, maybe an in agony selfie will do the trick…
