60's Theme day

I know my post 10 minutes ago said we’re not allowed to talk about our company, but I can’t help it. We just got another email about having a “60’s theme day” in which we’re encouraged to wear tie-dye and beads and the promo has “Flower Power” and peace signs on it. Now, I could be just young (not likely) and stupid, but wasn’t all that shit in the 70’s??
