Ride an elevator without stopping on every floor
If you’re in a hurry to get somewhere, then this trick may prove very helpful. But remember not to use it too much — other people have places to get to as well. To ride an elevator without stopping on any floors other than the one you want, hold down the ’close doors’ button until they close. Then press the button for the floor you want to get to, all the time keeping your finger on the first button.
