This may be a sign that the gas crunch is breaking the piggy bank.

A man trying to pay for gas with a sackful of pennies at a Denver gas station Thursday got so pushy that clerks called police.

The 7:30 a.m. call was on what was termed an “unwanted person” at the Diamond Shamrock station at Broadway and 10th Avenue.

Employees said the man, driving a satellite TV truck, became offensive as he insisted on paying with about $10 worth of pennies while the station’s mini-mart was busy with a line of customers and vendors delivering goods.
