I do most the cooking in my house, and the majority of it is meat and produce. I can say from years of experience that it's easy to grab a bad apple if you aren't paying attention or know about food quality, and from the grocery pickers I've seen, they aren't and don't.

A guitarist doesn't just buy some random guitar from amazon - they see it in person and play it. If you cook and care about your food, using a food service just isn't something you'll want to do.
