Cashier Wendy Kile, 20, allowed a blatant case of line-cutting to go unpunished Monday at the Billings Road Safeway. 'I was waiting in line when this smart-aleck teen walked right in front of me,' said shopper Ida Sims, 43. 'I complained to the check-out girl, but she just said, 'I honestly don't care who I take next.' What kind of answer is that?' If Safeway authorities do not punish Kile for failing to preserve the integrity of her line, Sims said she will gladly take her business to the IGA on Brook Street.
