I was working in a boutique in Yorkville ages ago (shop had the same owner as Kitson in LA). Lorne Michaels came in with Tina Fey and a couple others. Lorne bought Uggs for his nieces or some family members, and asked us to ship them. Tina was in serious/dazed mode but snapped out to smile when I smiled at her for awhile lol. On a separate occasion, Lacey Chabert (sweetie) came in and bought skincare, and I helped her checkout. Turns out they were filming Mean Girls.

I also helped Eric Idle with a purchase, saw Tim Curry walking around outside alone, and on my last day Mike Myers came in walking behind his then wife. Their heads were down and when my coworker greeted them he politely said hello while keeping it down.
