Is Coffee the Persuasion Bean?
Gli7ch writes "According to an Australian study, our geek wonder-drink of choice might turn us into yes-men. From the article: "The experiments showed that "caffeine increases persuasion through instigating systematic processing of the message"." Apparently this has implications for the advertising world, "because it suggests that they should schedule adverts for times when people are likely to be consuming caffeine, such as breakfast time."."
I suspect one could hire a "gentleman's gentleman" in any major city, even ones where that kind of thing is illegal; try asking at your reception. Another option you may consider is getting a midget, you can store him in your hand luggage on long flights. Although I have extensive experience with gentlemen tending to my needs, I find that I much prefer self love whilst travelling. YMMV.
