Keep in mind that most Egyptian workers expect tips after performing a service, known as Baksheesh. This can be expected for something as little as pressing the button in the elevator. Many workers will even ask you to tip them before you get a chance. The typical tip for minor services is 50pt to 1 LE. Due to the general shortage of small change, you may be forced to give 5 LE to do simple things like use the bathroom. Just understand that this is part of the culture.
