I am so against meals for purchase in lounges. I think it is déclassé, lowering the standards of what a lounge should be. It's also a slippery slope.
When airlines first introduced buy on board, they lowered the standards of the free meals that were still offered. Within a short time, they published surveys that said (basically): "Studies have shown that people prefer buy on board offerings to the standard offering. So we are discontinuing the free meals."
