The amount of money that a cinema keeps from the screening of a film can vary depending on various factors such as the popularity of the film, the terms of the distribution deal, and the cinema's operating costs. Typically, cinemas keep a percentage of the ticket sales revenue, with the rest going to the film distributor. This percentage can range from around 50% to 70% for major blockbuster films, with independent and smaller cinemas sometimes negotiating for a higher percentage. Additionally, cinemas also make money from concessions sales, which can further contribute to their overall revenue from screening a film. **

To remove stains after removing the protective film, you can try using a mild detergent or soap mixed with warm water to gently scrub the affected area. You can also use a mixture of baking soda and water to create a paste and apply it to the stain, letting it sit for a few minutes before wiping it off. For tougher stains, you can try using rubbing alcohol or vinegar to help break down the residue. Remember to test any cleaning solution on a small, inconspicuous area first to ensure it does not damage the surface. **

To remove old grease and oil stains, start by blotting the stain with a clean cloth to absorb as much of the oil as possible. Then, sprinkle baking soda or cornstarch over the stain and let it sit for 15-20 minutes to absorb more of the grease. After that, scrub the area with a mixture of dish soap and warm water, and then rinse with clean water. If the stain persists, you can also try using a grease-fighting laundry detergent or a commercial stain remover. Always remember to check the care label of the fabric and test any cleaning solution on a small, hidden area first. **

Sweat stains themselves are not necessarily bad, as they are a natural bodily response to regulate temperature.

Sweat stains are discolorations on clothing caused by the salts and minerals present in sweat. When sweat evaporates, it leaves behind these substances, which can cause yellow or white stains on fabric.

Regular washing and proper care can help prevent and remove sweat stains from clothing. **
