People who enter the gaming industry frequently begin as gaming change personnel and booth cashiers, as these professions may be learned on the job. To work in one of these roles, you must be skilled with numbers because the entire day is spent exchanging coins for paper money, and proper financial accountability is a need in the casino sector. 

The gaming change guy wears a money belt or pushes a change cart around the slot machine area on the casino floor, dispensing change to gamers. When the jackpot alarm bell sounds and the jackpot exceeds the number of coins in the machine, the change person will work with the slot key person to distribute payoffs. 

Another aspect of the job is to ensure that the consumer signs a receipt for the payment. Change personnel have a difficult job because they are always on the go, moving back and forth around the casino's slot machine area. They frequently begin at or around minimum wage, but may earn more through tips. 

At the outset of each shift, a booth cashier gives change personnel with a money bank. The cashier at the booth also counts and audits the money drawer. Customers can also come to the booth to get change, cash in vouchers, and exchange money for chips. 

These are high-stress positions. Every step you take is monitored and recorded. You are constantly being recorded while on the casino floor. Both positions necessitate the ability to calculate and communicate fast and accurately, frequently in the midst of a lot of noise.
