Totally agreed. If you can get Swiss C on a reasonable discount it can actually be very good value for money given (for a late afternoon or evening arrival), it can save you having to go looking for a meal in a place you don't know. Plus, the ground services and lounges at ZRH (not to mention ZRH in general) are agreeable enough.
It's the people who have Gold cards who I think have a quiet laught at you as they walk past though (I should know, I have a gold card and normally fly Y).... They've had the lounge (and a hot meal, depending on the time of the day) and all of the priority services plus they've got the same type of seat as you. All they're missing out on is the meal and the TLC
