I just became familiar with the concept and term "bag check" (found it on one of the threads in here). Even watched videos on YouTube of bag checks. I thought it was fascinating how this seemed like a big deal to people. And, it was interesting to see how much stuff folks put into a bag. I knew pros did and maybe constant tourney players perhaps. But do a lot of players carry so much stuff? And, why do folks need to carry 12 or more rackets of all different types everywhere they play plus "stuff"? I just bought a bag (1st one, three pack) and it looks so inadequate...and OMG, the brand on the outside of the bag does not match the brand of my rackets. Does that violate modern tennis etiquette (my Prince rackets in a Wilson bag?). Just an observation from an old, reentering, & reawakening player.
