Seeing as you are holding urine in your bladder or even in your penis, you should be ready to let it out anytime so when someone is near by you may be able to go automatically.
Regarding a hierarchy plan, maybe 10 bathrooms is too many to start off with?
Write down at home a description of each bathroom, for example:
Mall bathroom: 10 small urinals with dividers
Work bathroom: 5 urinals without dividers
Bar: 3 troughs
Public convenience: 7 big urinals with dividers
Freeway services: 20 small urinals without dividers
You can code this in a diary by initialling each one, for example:
M.B: 10 s.u.w.d
W.B: 5 u.w.d
B: 3 t's
P.C: 7 b.u.w.d
F.S: 20 s.u.w.d
Begin using the one's you find less intimidating or plan your route like a map by listing the one's closest together, for example:
Use the bathroom at work, drink some water for about 30 minutes before lunch, go out for lunch, use a public convenience, have lunch, and finally go to a public convenience within 10 minutes prior to returning to work after you have had your drink and your level of urgency has risen.
If you think you can try something like this then have a go.
