I found the reverse, LAF.
One of my regulars actually lived very close to me - her premises were a couple of towns away. We'd often see each other out, usually her with bf, who didn't know. She was grateful for the blanking, but I always got a smile or a wave, if I was on my own. Got much better service, and often it was a prompt to go back and see her.
I currently see a different wg girl out and about in my own town, and the reception is not so good.
Horses for courses, I guess, but I'd go the blanking route and respect their privacy.
