Is it legal for a business to refuse to give you a receipt when you pay them?

 It depends on the jurisdiction and local laws. In some countries and states, businesses are required by law to provide a receipt for goods and services sold. Refusal to do so could result in legal consequences for the business.

In other areas, there may be no legal obligation for a business to provide a receipt, but it is generally considered best practice for businesses to do so as receipts serve as a record of transactions and can help protect both the customer and the business in case of disputes.

It's best to check the specific laws and regulations in your area to determine if a business is required to provide a receipt, and what your rights are as a consumer.
