Second correct answer in from Steve Bailey.

Third correct answer in from robertmee

so. When are you going to share the answer

I was thinking approx 48 hours after posting the question.

thanks for making feel stupid.

this is a good one.
in my defense I had a mini stroke last weekend.
bit guy doesn't know
word guy doesn't know
now they both know.

Solution (using Steve Baileys wording)

Based on the first statement from the café owner:
Café owner can't know the correct bit no matter which byte is correct because each byte has multiple bits as possibilities. However beef plant owner would know the correct byte if he had bits 4 or 5 since bit 4 is only used with byte 6 and bit 5 is only used with byte 5. Therefore bits 4 and 5 aren't correct. Neither are bytes 5 and 6 correct because if either were correct, the café owner would not have been able to say that the beef plant owner couldn't know for sure.

The beef plant owner can now state that he knows the correct byte/bit combination. That means the correct bit can't be 0 since that bit used with both of the remaining bytes.

Since the café owner can now say that he knows the correct combination, it must be byte 7, bit 2 since byte 8 has two possible bits remaining.

I had been thinking along those lines but obviously wasn't as sharp as Steve since I came out with another answer. Never mind, I enjoyed it anyway. Thanks for sharing
