.it is generally considered customary for shoppers to park their cars prior to going shopping. Surveys reveal that those shoppers who remained in their vehicles tend to be either (a) ram raiders or (b) Macdonald's customers.

For example, the stampeding buses on Edinburgh’s Princes Street tended to have the effect of focussing shoppers’ attention on (a) not being trampled to death, (b) run over at the next crossing (because the council had yet again randomly switched the traffic flows), or (c) the hideous buildings (rather than the majestic views on the other side of the traffic hazard).
