Taps 25: pull tap vs push tap

I received these photos from a friend who got back from Mexico:

The tap I found in a hotel at the airport at Guadalajara. You turn the top to set the temperature and then pull it out to make the water flow. I thought this was pretty weird seen as everyone is used to pushing taps to turn them on (aren't they?!). The clearly know it is unusual because, as you can see in the photo, they have to include a sign with instructions on it.

The design of the tap allows for (easy) pulling. Although the question is if it is easier to pull or push taps. Imagine a simple scenario. We have soapy hands and the water stops flowing. In order to start it again we need to pull. There are two things here: (1) it is hard to pull with slippery hands full of soap and (2) pulling the tap with soapy hands makes the tap full of soap as well (ever seen people in public bathrooms pushing a tap with a back of their hands?).
