No singles night at our supermarket of which I'm aware. Although I suppose Thursday would make sense for single guys who want to be stocked for the weekend beginning Friday night, in case "guests" drop over from the clubs.
BTW, our Wilton Manors Publix supermarket is packed with gay men at all times, singles & couples, this being a "gay ghetto" as the gay detractors here like to mock. It's so cute to watch couples doing domestic shopping together, and I'm not being facetious, it really warms my heart to see them. You just stop, stare and think: "WOW! What a beautiful couple they make! How lucky they are! I never saw that when I was younger, how lovely at least one little corner of the US has been able to defy Right Wing repression."
And we're pretty obvious about our own selves there, openly saying ordinary things like: "Do we
have enough potatoes?" "We already have milk, another won't fit in our
refrigerator". Making it crystal clear what we are, unless you imagine us 2 geriatric roommates. Plus we always run into gay friends there, we spend as much time gabbing and catching up on the community news as shopping.
I used to hate supermarkets (my late Father got into the boom right after WWII when I was growing up), but here & now it's a social outing to go gay grocery shopping, so that now I like it a lot more.
My dear Dad would probably die all over again if he saw this here. LOL!
