About every bigger hotel has a kitchen for employees. They also have a vending machine hidden somewhere, with sodas for just 60 cents. When strolling through the restricted area, just walk straight, slowly and self confident. Quote these phrases when an employer behaves nasty towards you. After first going into your room and checking it out, go back to the reception and complain that the bed is too small, the street noise is too loud, the view is too poor, etc.
Many good hotels offer voice mail to their guests.
The most popular system is Meridian Mail. Some hotels have an own dialup for the voicemail, but mostly the hotel just lets you access it through the main PBX operator. If you are unlucky you have to wait 5 rings at a number before the Voice Mail answers. Most guests don't use Voice Mail. The few that do also keep the default password, which is often the room number or the birthday of the guest.
