i would say that 'bans' is 'bananas' - althought could be 'buns', but with a dodgy 'u'..

I would agree that it is more likely to be short for "bananas". Although the writer forms their "a"s in different ways depending on the letter which follows, their "u" is consistent. What we are seeing here is a shortening of "bananas" caused by a common fear of getting into the "-nana" section and not knowing when (or how) to stop.

i agree vin, re the "-nana" problem. do you feel that "satsumas" was a lucky guess?

I don't think so. I would say that the writer of this list is literate and well organised. The nice oblique in the first line, the consistent use of capital letters and the neat spacing tell me this.
The bananananas problem is, in my view, not associated with poor spelling.

barnarnars is one of the few words i can actually spell.

I´d really love a pizza with cash as one of the ingredients. Not sure if i would eat it, though. Sure its a very expensive pizza.
