psg times two

this weekend i went to another pizza store and gave my phone number to another pizza store guy. neither has made messaged as yet, but you can see my dilemma, can't you?

hypothetical, much anticipated, but imminently possible message from a psg:

hi, it's psg from the pizza store. do you want to catch up sometime?

how the hell am i going to know which psg it is?!
