Do you wipe the input interface (e.g. phone screen, computer keyboard, payment terminals pin pad) after you type in the pin/password? (In order to hide any fingerprints/residue on the keys)

I mean like, after I type a password on a computer, I'd rub my fingers across the entire keyboard to make sure any fingerprints/oil-residues gets evenly distributed so its harder to know the password. Same with phone unlock codes, I just use my fingers to rub against the part of the screen where the virtual keyboard was displayed.

Am I being weird? I've had this habit since the first time I got my first digital electronics.
