In one sentence, describe what the following article is about:

Some hotels may refer to the front desk simply as “Reception” or the “Reception Desk.” This is normally located near the main entrance of the hotel where you checked in for your stay. With your baggage in tow, go to the front desk worker, give them your keys, and settle payment for your stay.  When you arrive at the front desk, say something like, “Hi, I’ve been staying in room 222 and I’d like to check out.”  Ask for an itemized receipt for your total bill. Fraud is relatively common at hotels. If your hotel refuses to give you a receipt, this may be a red flag.  An itemized receipt is generally required to get reimbursement for expenses on a business trip. Be sure to ask for one when traveling on business. More and more, hotels are using online tools to make your stay more convenient. Some hotels may offer an online checkout. To find out if the hotel you’re staying at has an online checkout, look for this information online at the hotel’s website or ask the front desk. Many online check out services will send a bill to your email address, though you may be able to request that a physical bill be sent to your home. If you’ve decided to pay cash for any of the services you’ve received at the hotel or to resolve penalties, ask for an itemized receipt. Compare this to your total receipt to make sure you weren’t charged twice for the same thing. If a “clerical error” occurs and the hotel doesn’t have a record of your payment, you may have to pay this fee again if you don't have a receipt.

Summary:
Check out with the front desk. Check out online alternatively, if applicable. Get a receipt for any cash payments.
