Bonkers. But not a surprise at Stansted.
A bit like Dartford River Crossing charging bikers 30p/crossing when they had the kiosks.
Must have taken me a minute to get the bike into neutral, undo glove, take it off, remove pre stored 30p in coins, pay cashier, replace hot glove (not easy sometimes), get it back into gear then ride off.
All for 30p. Meanwhile frustrated car drivers behind me.
Bridge crossings in Europe generally free for motorbikes.
