Maybe a standard planning requirement

or a standard licensing requirement which could be added if the
licensee wanted a change in the licence, e.g. to allow for longer
opening hours. The Licensing Act applies if the premises serve alcohol
or 'late night refreshments' after, IIRC, 11 pm, even if they don't
sell alcohol.

Plus only a complete lunatic (or a particularly twisted sadist) would
design anywhere that sold alcohol for consumption on the premises
without toilets - the consequences for the surrounding area would be
horrific.

TBH I don't see why people object to pay bogs, it's not as if 30p is
exactly going to break anyone's bank and paid-for loos tend to be vastly
cleaner and better maintained, and rather less likely to be occupied by
undesirables, than free ones. Free loos within paid areas (as in
trackside or in pubs, beyond the barriers in cinemas, etc) make sense.
But public ones are just nicer when there's a fee - gives the owners
both a revenue stream and an incentive to keep things civilised.
