While it is better to err on the side of caution, there is a bit of overthinking here. Like Mikey said, send what has been agreed upon and, if some "hitchhikers" or "bodyguards" just happen to ride along, hey, nothing wrong with that! 👍 Keep it simple, keep it within your budget. On the other hand, if you feel that someone is going out of their way to help you out, well, like at a restaurant with excellent service, tip accordingly.
Eventually you'll come up with your own comfortable levels and laugh when you look back at this post.
