I've talked on the shitter. I heard someone dying and asked if they needed help, they never replied, just did up their belt and fled in panic. Never again!
A few months ago I went to a steakhouse with some friends and learned that 3 ladies from the wedding party in the party room had had too much to drink and were sharing a stall (small bathroom with only 2 stalls) puking their guts out for a solid 20 minutes straight. As we paid and left we saw the paramedics arrive to escort the ladies off of the premises and an employee poised and ready with cleaning supplies to begin cleaning up the wreckage their stomachs had wrought upon the porcelain.
