Funny story..
One Shabbos morning my uncle responded to a Hatzala call in a shul like the one explained. They had a kiddush and one of the congregants offered my uncle a drink. My uncle responded “I’ve got to drive back, i wont take one thanks..”
The congregant respnded “That’s OK I am driving back too!”
BTW in their community there is not always a Shabbos goy to drive the car back..
