Hospital robes

Early wake up to get a cup of tea in before a 2 hour ban on liquid prior to a "Barium swallow". I always find it unnerving to go into a cubicle, get into an alluring robe, lock the door, and then get called out the other side. Why on earth can they not design the robes with tapes where you can actually reach to tie them?
Have to say the barium swallowing was not pleasant but there are far worse things.
Went straight back to work, which in hindsight was not a wise move, as I felt pretty queasy and stomach churning for much of the day.
