Is 'and' ever not a conjunction? [closed]

Certain dictionary definitions of 'and' in lower-case letters are as a conjunction. In capital letters 'AND' is a noun as a Boolean operator. Below is an example of a request to a sign creator for a sign of symbols for Fish & Chips.

Please give me symbols for: fish, 'fish' and and, '&' and chips, 'chips'.

In that example the word 'and' can be said to appear four times in a row. That first use of 'and' in the example sentence was as a conjunction why was it not a conjunction for the other three uses of the word 'and'? Other users commented about 'and' as something other than a conjunction. What is 'and' other than a conjunction?

The Oxford English Dictionary lists "and" as conjunction, adverb, and noun.

The adverb is labeled "obsolete".

Ye shall see and what somewhat I have in my sacke.

The noun could be an instance of the word "and"

ifs, ands or buts

Also the noun "and" may mean the boolean operation AND.

Yes, it is not a conjunction when it becomes a noun (or other) in usage or function.

Normally...

And

is a conjunction, except for when it is being quoted as a word.

-Cambridge

As @Mitch mentions in a comment,

See Use-mention distinction. In short, 'and' is a conjunction, but " 'and' " is word that means a conjunction, which may seem like caviling but is an extremely important distinction. You can put a log into a wood chipper, but you can't put the word 'log' into a word chipper.

Edwin Ashworth said:

"The 'word-used-as-a-word' is usually classed as a noun

Edit

I have been thinking on Mitch's comments.

I have heard "and" used as a demand for information: possibly it could function as an interjection.

Ex.

"Did you pick up your sister at the bus station?" "I went there..." "And??" She wasn't there."

Final Notes:

Some folks here have noted in the past that although dictionaries list Parts of Speech, they don't do a particularly good job of it.

Yes, it can be a noun, like if I were to say:

"And can be a noun— no ifs, ands, or buts!"

"No ifs, ands, or buts" is a common expression. With that in mind, it's obvious the word "and" can be a noun because the word "and" has been pluralized. Conjunctions don't have a plural case. Nouns do. "And" being the subject of "can" above — so doubly proving its nounness — is the icing on the cake.

Incidentally, any dictionary will tell you it can be a noun. Scrabble dictionaries even do since pluralizing "and" by adding an S in order to build in a perpendicular direction and get the points for "ands" in addition to the new word being formed is a strategic move.
