To think parents lying about their child's age to get cheaper tickets is wrong?

[Liketochat1]

The swimming thread got me thinking about a chat I was having the other day. Parents were saying they lie about their child's age to get cheaper or free tickets to parks, zoos, shows etc... They claim their children are under 5, 3 or whatever when they aren't.
AIBU to think this lying is wrong and unfair or is it just to be expected?

I do admit to doing it, when one of my dcs has been 2-3 months over 3 as they were still in a pushchair and didn't get much enjoyment out of rides etc due to napping.
But i wouldn't be brazen enough to attempt lying if my dc were much older

And tbh its all about making a tonne of money by charging the same price for a 3yo as a 12yo which i think is completely unfair- A 12 yo gets much more out of it
