What Type Of Food Do Golfers Keep In Their Bags?

On the last episode of LCB, we reviewed 'Luca', went over some news AND we talked about what types of food pro golfers keep in their bag.

I grew up poor, so golf was not something I could ever consider playing. Plus, my old man is an extremely blue-collar, baseball only purist so it was never on TV. Since then, I've gotten more into golf thanks to conduits like Foreplay. I'm still very much ignorant to a lot of how the golf world works, though. For example: I just assumed that the bags were only for clubs. Can you imagine the chaos if a Nature Valley bar gets loose in one of those? You just gotta throw it out at that point! But luckily, rich kids Trillballins and Jeff D counterpointed that pros have insulated pockets in the bag that they pull food out of all the time. This DJ picture was used as an example. 

My question (which comes from someone who is once again ignorant of Golf), is what is the go-to golfer fuel? It has to be something better than peanut butter and jelly between two slabs of Nature's Own whole wheat bread. These guys are rich, professional athletes! They should be pulling out some surf-n-turf, fillet mignon, caviar!? Jk….unless???
