Buying tickets with cash. In the past they charged a transaction fee just to those paying with credit and debit cards but EU regulations prevents them from doing that. So, rather than removing the surcharge from credit and debit card payments they have extended it to all forms of ticket purchases.
I wonder what the make up of ticket purchases is? Obviously, not being local, I never buy tickets over the counter and always put them on my card and I'd have thought most buy online or over the phone like I do, but maybe I'm wrong.
