There are several places where you can get single dollar bills. Here are some options:

1. Local Banks or Credit Unions: One of the easiest ways to get one-dollar bills is by visiting your local bank or credit union. Simply go to the teller window and ask for singles [1].

2. ATMs: Some ATMs offer different denominations, including one-dollar bills. However, it may not be common to find ATMs that dispense one-dollar bills. It's more likely to find ATMs that dispense higher denominations like $5 or $20 bills [2].

3. Car Washes, Laundromats, and Arcades: Places where coins or tokens are commonly used, such as car washes, laundromats, and arcades, may have one-dollar bills available for change [2].

4. Self-Checkout Lanes at Stores: Many self-checkout lanes at stores have the capability to make change and dispense one-dollar bills. If you pay with cash and have a remaining amount to be paid in cash, the self-checkout machine may provide you with one-dollar bills as change [2].

It's important to note that availability may vary depending on your location and the specific establishments you visit. If you have an online-only bank, it may be more challenging to obtain one-dollar bills, as online banks typically do not have physical branches. In such cases, you may need to explore alternative options like using cash-back options at stores or asking friends or family for one-dollar bills.
