I regularly order fruit from these guys and can attest that it's all very good quality. The banana sampler in particular is one of the few ways I can actually get a good variety of bananas outside of being on holiday.
In my experience it's just that other varieties just taste better. The Cavendish isn't bad, strictly speaking, it's just grown because it ships and stores very well.
The best part about this is that archaeologists supposedly found more complaint tablets in the same room of the house about the same guy, leading them to believe that the house they found them in belonged to the Ea-nasir himself.
Don't kid yourself. People can and do disagree, but they doesn't preclude the fact that astroturfing absolutely does happen as well, and it's absolutely a problem.
