How to be a good hostel guest

I stayed in a 10-bed dorm in a nice hostel last night. I couldn't sleep though because of cell phones.

First a cell phone kept going off on vibrate while a guest was in the bathroom. Another cell phone had 3 or 4 text messages come in with a loud musical chime. A 3rd guest answered her phone in the dark room at 12:30am, about 2 hours after I went to sleep, talking for about 5 minutes in her bed. When I woke up again at about 2am, it was because she was tapping away on her cell phone in her bed, sending text messages.

If you were making a list of advice for people on how to be a good hostel guest, what items would you add? I was laying in bed last night after being woken up thinking about it.

Here are just a few courtesies that I wish more backpackers would follow -- they should be obvious, but I keep running into them:

• Turn off cell phone before going into a dorm room where people are sleeping (ringer off and vibrate off)
• Don't send text messages or tap on a laptop keyboard in the dorm room when people are sleeping
• Don't burn anything in the dorm room (cigarettes, incense, mosquito coils, etc.). Other guest may have chronic respiratory problems like asthma or bronchitis.
• Don't spray deodorant in the dorm room for the same reason -- and it wakes people up
• Don't talk in the dorm room when the lights go out, or when people are sleeping
• Don't turn on the dorm room light after people are sleeping. Use a flashlight or the light from a cell phone screen.
• If you have to check out early in the morning, pack the day before.
• Don't rummage around with plastic bags in luggage when people are sleeping.

Is there anything that you wish backpackers were aware of before they stayed at your hostel or in your dorm room with you?
