I had a lady stop in my shop the other day with two frames that she wanted mirror cut for:
Me: I can do that for you. Can I just get your name & a phone number to reach you at when it's finished?
Her: gives me this confused look Oh, well, I've been here before. Am I not in your system?
M: I don't recognize her, so she's not a 'regular' customer Sure, if you've been here before I should have your info somewhere, but I still need to ask so I know who you are and can pull that info up and make sure that it's up to date.
H: Huh. I've definitely been here before, so I should be in your system.
M: internally notes that she still hasn't given me her name Right, but I still need your name & number so I can confirm who I'm doing the work for and who to bill it to.
H: still has a mildly perplexed look on her face Oh yeah, sure. I'm BlahBlah & my number is 555-5555. I mean.... I've been here before so I should be in your system.
M: ignoring the last part Okay, thanks BlahBlah. It might take a couple days, but I'll call you at that number when I have it done.
She thanked me and left, and I had to chuckle at the idea that since she's 'been here before', I should remember who she is without asking her name.
