Don't do it in most circumstances. The last time it happened to me, changing date venues was a disaster. I met a woman from Ukraine in a U.S. bookstore and she pulled this maneuver on me about 30-60 minutes before a date happened. The date ended up at a place with poor logistics and I ended up seated at a table instead of side by side at a bar. She also managed to order food, and fidgeted with her phone a lot. She was a bad person, but it didn't help the cause that I lost control of the logistics there.
