Sometimes personalities clash through no fault of anyone and it's better to just go their separate ways. I grant I'm biased here -- Steve seems to be amazingly calm, almost zen, and I can't imagine him getting worked up for a petty reason.Steve seems to be the kind of guy who manages to find a positive in most situations. I mean, for most ration packs, even the old ones - he'll find *something* to get excited about or try to get some good from it. He very rarely pans any of the rations he gets unless they genuinely are bad. Heck even the ones most people would say no to , steve will still coo over. I mean the guy tried to get something out of 100+ year old beef.
I did notice on one of the older videos, he's gone back to note he's no longer associated with the MRE museum or something. Wonder what happened there.
Also, looking up 'MRE Museum', I assume you mean these people? Because their website seems VERY barebones and under 'Our Staff' they don't have anyone listed. I wonder if Steve saw something that didn't pass the smell test and decided to jump ship before he got caught up in it.
