I'm assuming that by "bad for the environment" she was referring to the production or the landfilling of them, not littering. Either way tho, it's bad form not to let the customer themselves decide whether they want to use a lid. If she felt so strongly about it, she could have supplied more environmentally friendly lids and put a sign above them telling you how bad they are for the environment and to only use it if you need it.
