and
There should be more space between "fish" and "and" and "and" and "chips".
It refers to a poorly spaced sign reading 'fish andandandand chips,' suggesting better spacing between 'fish' and the repeated 'and's in 'and chips.'

Meanings

the same word, phonetically reduced in casual speech — almost always the form actually spoken in connected English

Word origin
From Old English and or ond, the inherited Proto-Germanic conjunction (*andi-), cognate with German und, Dutch en, and Old Norse enn. 'And' is one of the oldest unbroken words in English, traceable in continuous use for over 1,200 years.
Fun fact
Despite its constant appearance in writing, 'and' is rarely pronounced /ænd/ in connected speech — the unstressed reduction to /ən/ or even just /n/ is so common that English speakers often don't notice they're using it. The contraction in 'rock 'n' roll' is one place this reduction is preserved in writing.
