Should I be worried that I won't be given a receipt if I pay with cash?
There are number of reasons why someone doesn't want to give you a receipt for cash payment. Anything ranging from not wanting to pay taxes, to being able to deny you gave them money for service in the event you're not happy with the service and ask for money back. You won't get in trouble for giving him cash, however you should be worried because any "reputable" person providing any type of service/product will provide a receipt regardless of payment type.
