Perhaps the threads can return to decent, focussed, adult discussion now.
I'm not sure what the fuss is over paying for trolleys, to be honest.
On recent travels, I've seen similar at various airports, including some where I could even swipe my credit card to pay.
If revenues are falling from the airlines, it has to be sourced from elsewhere, and what better or easier source than a captive audience; the humble passenger?
