Speak up. If there is a problem, speak up or else it will not get addressed. The supervisors try their best, but they are not mind readers. They won't know what's going on, with either you or some other issue in the zoo unless you tell them. It would also help if you made some friends that you aren't afraid to ask questions frequently because, like with any job, there is a lot of information to absorb within the first few weeks and you might not get it the first time. If you are serving tickets and counting money, be sure to be extra careful with the count. Count your money throughout the day if you can. If not, make sure to double check the cash you recieve from customers and the chnage you return to them. You are responsible with the company's money after all, so accuracy is important.
