After a fair rack of thinking I have decided it it not worth running.

Also, as I'm Silver I get 25% off lounge access, so Lounge25 is only €34, and I have some miles that I'll never gain enough of for a reward flight, so I spent a few of those (at a terrible rate, but I knew that) to get into Lounge25 for 3hrs for €25. Had I stayed airside and not loungeside, I would have easily spent €20 on food anyway given the length of the layover, so it makes for a good deal.

I'll eat till I feel sick and then won't have to eat a meal in Munich later in the day, so really its saving me money.
