Actually, if as a member of an audience for any event
at any 'venue', [wherever it may be]
I'd pay good hard earned money to travel to,
pay to enter,
and possibly even as a last resort [if the 'Entertainer' merits it],
pay for overnight accomodation;
then surely, more than just a matter of mere opinion,
I'm reasonably entitled to regard that event as a 'gig /concert'
and have reasonable expectations of the quality
of the whole 'entertainment package' provided !!???
