Should Laundromat still be capitalized if following English grammar and spelling rules?

"Laundromat" is a proper noun, specifically a trademarked term for a self-service laundry business. Therefore, it should always be capitalized, regardless of where it appears in a sentence.

Here's why:

* Trademarks: "Laundromat" is a registered trademark, and trademarks are always capitalized.

* Proper Nouns: Even if it wasn't a trademark, "Laundromat" is a specific type of business, similar to "Xerox" for a copier or "Kleenex" for a tissue. These are proper nouns and are capitalized.

Examples:

* I went to the Laundromat to wash my clothes.

* The Laundromat is open until 10 pm.

* There's a new Laundromat on Main Street.
