I remember once reading an article in The Straits Times about the life of a bus captain, and he (the bus captain) related how, once, when he was driving route 24 towards Changi Airport, he had to hold back all of his urine until he can't take it anymore and was running for the toilet at terminal 1 when he reached there (bus captains usually have their breaks at terminal 2). Apparently, he dranki too much soup (if I remember correctly) before the trip.
Yes, different material, but similar case
