When choosing a room at a love hotel, I assume the rooms with the lights off are occupied, so you choose from the rooms with the lights on. Do the prices vary depending on the room’s size, décor, amenities, and so on?

Are you not familiar with Google? There are convenient services like Google and Yahoo. If you enter keywords for the information you want and hit the search button, they’ll list websites related to your query. You can even type it into your browser’s address bar and search that way. For example, simply entering “service time” will give you the answer you’re looking for. It was probably good that you exercised some self-restraint and refrained from asking your date right then and there. But since both the readers and respondents on this Q&A site are human too, I’d appreciate it if you treated us accordingly. Then again, if you asked a woman you’re close enough to be dating, a man might even think, “She’s over 30 and doesn’t know this? How cute♡”
