As loyal readers know, Apple stores are not particularly cash-friendly; in the case of the iPhone and the iPad, they're downright cash-hostile. Both devices require a credit or debit card for purchase, although you can waltz down the block and buy an iPad with cash at Best Buy if you like (and you can use a gift card for iPhone, but not for iPad).
There are some points on Apple's side for the pay-with-plastic requirement (the primary one being that it's hard to enforce the two-per-person purchase limit without some way to track buyers), but it's clear that the rule is a source of annoyance to some potential customers. Now the annoyance is getting magnified.
In a post that is destined to be enshrined under the Wikipedia entry for "irate screed," David Gewirtz at ZDnet reacts to this KGO-TV story about Diane Campbell, a Palo Alto woman who tried (and failed) to buy herself an iPad using good old greenbacks. And when I say Gewirtz reacts, I mean he absolutely goes medieval about this "outrageous" miscarriage of justice.
