It's kind of creepy to do anything to a photo without consent. I'm a dude with plugs, and it'd be a little off-putting if a stranger I didn't know digitally removed my ear rings to see what I'd look like.
This is how I present myself. You can see me without ear rings or makeup when I want you too.
Maybe Subway doesn't have a sustainable business model if they can't maintain profits while paying people a liveable wage.
