I hate people who break the urinal unspoken golden rule
Assuming its a 6-urinal setup
1.1 - If all urinals are unoccupied, thou shall only use urinal 1 or 6.
1.2 - If urinal 1 is occupied, thou shall only use urinal 6.
1.3 - If urinal 1 and 6 are occupied, thou shall only use urinal 3.
1.4 - If urinal 1,3 and 6 are occupied, thou shall pretend to fix ones hair in mirror until one of these occupied urinals open up.
1.5 – Rule 1.4 will always apply if there is not at least a one-urinal buffer between you and someone else.
1.6 - If you really must go when rule 1.4 applies, use the stall.
1.7 - No conversation and no singing
1.8 - Absolutly no peeking "Big No No" .
