1. One accepts only Visa, one only MC, one only Amex, one only cash, and one only accept bitcoin.

2. One offers bananas to walk in visitors, but the others have a minimum wait time of 1 month to a year.

3. One is a mile away. One is an hour away. Still in the same county.

4. None of them offer an easy to understand menu. You can't just order a banana. You ahve to order Banana Services and meet with Banana specialists. You can't take the banana home.

5. You wake up in a banana shop and you didn't get a chance to shop around before being presented with a bill. They don't take your payment of choice, so it's 10 times as expensive.

6. Some won't let you buy a banana. Instead, you have to buy a banana service. Per banana pricing is the lowest here, but the total cost is higher if you just want a banana.

Which banana store do you buy from? A, B, C, D, or E?

I'll take the first choice you make and let you know if you picked correctly. Anything other than the correct choice is a failure.
