[tanelaine]

Thanks, Sandy.

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

You say it should be 'are', but what about the first part - Should it be 'and; or 'or'?

[Calibax]

It should be food AND drinks are not allowed as both are prohibited

[boxtops]

Rephrase it altogether:
Neither food nor drink purchased outside the premises will be allowed inside.

[Bummle]

How about "Neither food nor drink purchased outwith these premises will be allowed"

[boxtops]

Snap bummie - but outwith is a very Scottish word!

[DTCwordfan]

I too recommend a rewording:

"Yer nay bringin' that ther' shyte in here, Jimmy"

[Bummle]

Great minds think alike, boxtops! Ay, it is indeed.....

[Prudie]

^^^ see DT- male humour!

[boxtops]

Away and bile yer heed, DT.... (birthday or not!)

[DTCwordfan]

"Bedankt," Ladies.....

[Bummle]

haha, DT, that should dae jist fine!

If you didn't buy it here, don't try it here.

[jno]

why not just say "and" rather than "and/or"? It should be plural for preference, but this would eliminate the ambiguity. Nobody goes to the counter and says "Can I have some food and/or drink, please?"; it's just a legalism.

Or just "No food and drink from outside the premises".

[boxtops]

if it's not sold on the premises, you can't consume it here.
