Help me figure this out

I saw a truck today with writing on the upper corners.

On the upper left corner it said:

Gourmet Chips
And Pretzel's

and on the upper right corner it said:

Healthy Foods
And Drink's

So... what, exactly, did that person think the apostrophe is for?

Also, don't want this getting lost: My credit union is asking us all to contact our congresscritters. Honestly, maybe I should buy a book of postcards. Of course, my handwriting is terrible....

Okay but seriously I don’t understand the logic they’re working with!

[dine]

there is no logic. people treat them as if they're decorative, with no actual connection to the grammatical rule. if it ends in an "S", best throw in an apostrophe, just in case

[conuly]

Sure, but what about the other two words they didn’t do that to?

[glaurung]

The sample size is small, but it looks like the rule in their head is, a plural ending in S gets an apostrophe when it is the last word?

So they’d write “milk and egg’s”. But not “egg’s and milk”.

[steorra]

Another possible rule is that the apostrophe is only for "longer" plurals, i.e. plurals where the base word is more than 4 letters, so "Chip" and "Food" are too short for an apostrophe. (It can't be based on syllable count, obviously.)

I also wondered if it's based on anything about the class of sounds the word ends with, but I can't find anything. It would have been interesting if it was only after voiced sounds and not voiceless ones, or vice versa, but that doesn't work.
