Which words in bold should I use?

[Tan Elaine]

Food and/or drinks purchased outside these premises is/are not allowed.

Which word in each case should I use?

Thanks.

AND/ ARE

Actually OR/IS is just as acceptable.

I wouldn't use "is" in that sentence.

[Tdol]

I wouldn't use is after drinks either. It would work fine with food and drink for me.

Food and/or drinks purchased outside these premises are not allowed.

What about 'and' and 'or', which word would you use?

[SoothingDave]

Or and are.

If you say "food and drinks" then logically one could argue that the prohibition does not apply to just food or just a drink.

You'd have to be a smart alec to make that argument though.
If you say "food or drinks", you could take food in, and argue that, given the choice, you chose to interpret it as being drinks that were not allowed.

Guilty as charged!

I do work with Boolean logic, so the way I read an "or" or an "and" may not be the same way a "normal" person would.

I agree.
