Push, don't pull

A 'comfort stop' ahead of a crucial meeting caused a moment's unwanted panic-induced hilarity. Picture a designer gents in a swish office block. Floor to ceiling cubicle doors with polished steel handles and door locks. Entry was successfully effected, but on trying to leave the door refused to open. Fearing a broken lock, I slowly turned the lock while trying the handle, all to no avail. Taking a moment to reflect - and also envisage calling for help and being rescued by security - I returned to the door, only to find that it opened outwards, so my frantic pulling was no use whatsoever. A small push sign would be a welcome design addition...
