I would love for a strong bull (smooth operator) to approach my wife in the grocery store! It would be better if he was nice looking, respectful, and just casually strike up a conversation with her.
Maybe saying hi its a nice day or I have been looking for ??? or you remind me of someone.... or nice outfit, I like your boots or shoes, where did you get those..... Then just start talking and as you start feeling out where its going (whether she is still standoffish or getting into it, you will know by the vibes) then go from there, but always leave her with a business card or som kind of contact info to get back with you. Who knows maybe you will get lucky
