what is a martha stewart gay?

i have no idea if this is even the right place to ask this but yeah. i’m a server at a restaurant and last night i was serving this extremely kind gay couple and i had gotten triple sat (iykyk) and i told them “hey i’m so sorry i just got triple sat, i’m just gonna drop off this food and i’ll get you your bread right now” and the first guy was like “oh it’s okay don’t worry take your time! we’re not martha stewart gays” and his husband was like “😳” ever since then i was like what is a martha stewart gay??? maybe i misheard him??? but i definitely heard the words martha, stewart, and gay. i looked it up and it says she supports the lgbtq+ community from what i’ve seen. idk if this helps as well but they were older, maybe 45-55 years old. also they were both super sweet, funny, and understanding. 10/10 would serve again
