It was about two weeks ago when Blanca Lopez offered the two cleaning workers in her office building a little cash for trash, according to the cleaning company. Lou DeLeon, general manager of P&R Enterprises, gave this account: Lopez offered about $ 50 each for the paper coming out the door at the Association for Competitive Technology (ACT). Just bring it over to the offices of Upstream Technologies, on the same floor, she said. When they declined, she sweetened her offer to $ 500 apiece--with an extra $ 200 for the supervisor. They refused again.
