Why oh why oh why can gigs not finish on time to catch the last bus? No good complaining about soundchecks overruning - sometimes the gig doesn't start until an hour after the doors open; sometimes the doors aren't scheduled to open until 9.00pm.
No point praising yourself for charging only 3 or 4 pounds for entry to the gig if it's a tenner for a taxi.
No point saying the first band can't start until more people have arrived...some people will choose not to attend the gig because it finishes too late.
No point saying it's Friday/Saturday...buses don't run any later and taxis are more expensive.
Sort yourselves out.
