[MF] Experience with sex/hooking up in a restaurant

I’ve been talking about getting naughty in a restaurant with this girl for a while but am not quite sure how to approach sexual activity under the dinner table/in a booth/in the bathroom of a restaurant. Does anyone have any or know of any stories or tips for me to help plan this? Me (28M) and my girl (26F) are really into the idea but not sure how to approach seeing as the restaurant situations can sort of be hit or miss given table layouts and customer activity etc. – any help on this subject would be appreciated. Even if it’s telling me another sub to post to… Thank you!
