What's more fuel efficient ?

I've had proper (salmonella) food poisoning, that came directly from food. A dodgy tuna sandwich since you ask.

 

I'm also old enough to have drunk in pubs pre-dishwasher. It was reasonably common to get mild stomach bugs back then, often attributed to a "mucky glass". Those whirring brush things were the worst culprits.

 

A modern dishwasher uses very little water or energy to run. It also produces cleaner dishes.

 

if the glasses were mucky they weren't washed properly thats no argument for a dishwasher. The mild stomach bugs could have come from the beer or stress or something you ate. You can't assume it was the mucky glasses.

 

Food poisoning on the other hand is very obvious and relatively easy to trace
