No. Not pompous at all. People have a choice. Go there or if they can't be without their meat, not only for 1 and half hour, don't go there. Moz chooses the venues on his conditions. If they are not willing to agree on them there is no contract and no Moz.
I think if you really start digging in you will find that a big majority of them agree. I'd say 90 percent.
They, the venues, are calculating and apparently they'd rather have Moz without the meat, than meat without the Moz.
And, they are not crazy. They know it is an issue that is a concern to much more people than in the past. They adjust. There is another reason.
Many of the venues that rely on concerts and all other musical, or artistic performances, need the money, and prices of tickets for life music are so much higher cause that's the only way musicians can earn some money after internet has decreased their income from recorded music.
Before that prices of tickets for life music were a lot lower.
I remember last time when Moz did a concert at Tivoli in Utrecht in the Netherlands. It is part of a cultural centre also subsidised by the city. Not for the venue itself but a part of the income from tickets will be used to finance other cultural activities.
The venue had agreed with moz about meat, and meat products not being sold at the day of his performance and they kept their promise.
On that day there was also a classical music event with some well-known classical musicians and a show master/presenter that suddenly found out he nor his illustrious guests could have any meatproducts during the fancy dinner.
He started to twitter and said he was embarrassed in front of his guests and he wondered how it was possible some minor alternative musician, which he considered to be an extremist could just lay on his extremist rules to the whole centre, ha.
Than the social media storm began. If I would sum up in one sentence the opinion of almost all people it was like: he is a terrorist worse than ISIS and he should be killed. Freedom was at stake!!
But the venue did not react to that otherwise than saying there was a contract and both parties fulfilled that contract.
The venue was pleased of the sold out concert and with ticket prices of 65 euro they earned much more money than with the classical music event. No dig at them offcourse. And the venue had debts and that was a concern too for the city.
I don't think Moz knows about the fuss but I do know he likes to perform there and it was a great concert, believe me, I was there.
Edit:
Is this coincidence or what?
One day after I posted the info above about Tivoli in Utrecht it now has been made public an employee has been arrested for stealing 80.000 euro from Tivoli.
It was publicly known the venue had debts and was in financial trouble.
The city therefore had decided to back up Tivoli financially.
