Yeah you have a point lol. I know many places that will take cash but exact change only like bridge toll booths lol. Keeping change was always an issue, sometimes we'd have to send a guy out to the local bank to change out big bills for small ones. For hollidays we'd have to keep thousands of dollars in small bills just to keep up. I'd always ask customers for smaller bills if they had them. Its overhead and in some areas a danger to have more than a couple hundred dollars available.
