We visited the Zoo Lights last night and had rented a wheelchair for my mom. Rental rules are $10 no big deal, leave ID for return the equipment (completely understandable); however when returning the chair the staff had either lost my ID or worse given it to someone else. The employee in the booth had a very bad attitude as if I was the cause of her line getting long and impatient. The next person in charge said nothing and called for park management. At no time was their a "we are sorry", nor did they ever make any effort to make it better for the inconvenience they have caused me. Perhaps this happens so often they do not need to train staff of how to handle this and just go with "well nothing we can do and deal with it yourself" mentality.
