Assume you have all the luxuries of a modern life in your Tardis (toilet, hot showers, TV, books, game console, …) which doubles as a mini self-sufficient apartment with it’s own energy stores and generation.

Haha, I’d ask! If it’s a tardis, it should be translating and making me look like I fit in, yeah? At least clothing wise. I’d be a pale weirdo in a lot of places, but it should work! I’ll ask if I can visit, and bring them…wine works, right? That’s pretty ancient and won’t raise questions. That I’d answer with “it’s a gift from far awaaaaaaay” very awkwardly.
