Inevitably they end up with half a cart of things they 'don't want' which the store has to restock. The cashier's performance will be in the toilet because they've had to scan and remove this and that and this and that, other customers get irritated at the delays... worse is when they don't know their pin number and the system locks them out for 24 hrs after too many failures.
The freeloaders in my county are experts at gaming the system.
They only need that one ‘ticket’ a baby, and then they’re all set. Don’t need a job, just a Section 8 voucher for a trailer rental, Get that WICs voucher, SNAP and apply for TANF, and they have a disposable income that is more than the cashier they have checkout their booty. All too many of them are under 25, many in their teens having learned the scams from their mothers who do the same. It is a pitiful situation to see so many succumbing to sloth and freeloading.
