I’m not religious personally but TGI Fridays is a very popular after-church spot (according to all of the religious/former religious people I asked). Why are none of them mad about this?
How could they actively support a restaurant so sinful it includes a sin in the title?
It’s singular, but (strangely) possessive. Like, O’Malley’s implies O’Malley’s Bar, this would be the restaurant that belongs to TGIF.
It’s not possessive without an apostrophe.
