I agree, although I think that it's more a case of them being too impatient to allow others the time to see what they are purchasing. Of course, the old 'me first' and <insert appropriate expletive here> to everybody else is still alive and kicking. It's only under the cover of social media anonymity that they have the nerve to utter such abuse.
And if they are in a hurry there's always an option - "Excuse me, please, I need to get back to my shift in 5 minutes, could you just step back while I grab a sandwich? Thanks."
