A few to add:
The pub blaring Does Everyone Stare at obnoxious volume from speakers on the pavement isn't necessarily the right pub.
Do not mock the lady with the antibacterial handwash. She's right.
Your inability to converse in anything other than english and bad french is embarassing. Fellow europeans are stupendously gracious about this.
Queuing for general admission can be fun. If there's loo.
People you have never met will pick you up from an airport at midnight, at less than a day's notice, drive you several hundred miles to a gig, sort out a ticket, find you a hotel room, feed you and give every appearance of enjoying the experience. When you get home, other people who haven't been able to make the trip will drag you out for the evening to share your glee. So stop being so bloody cynical about people.
Pay attention to the trajectory when discarding cig butts from a vehicle in motion, as re-entry can cause distress.
You aren't too old to gig. You aren't to old to travel insane distances to gigs. You aren't too old to drink. You aren't too old to stay up late yacking. You ARE too old to do all the above simultaneously to excess. And you had better be wearing comfy shoes, taking vitamins, and drinking a hell of a lot of water.
Cheese should not be stored for two days in a cooler in the trunk of a car during August.
Whatever you order at a diner will be approximately four times more than you need or want to eat. And you will just have to live with the look of disappointment on the face of your waiter as you then decline the offer to take the leftovers away with you.
Instead of accepting bad hair, once in a while allow yourself to be persuaded into a salon the day before a gig, where someone will get it under control for you. Do not allow yourself to feel like a traitor to the feminist sisterhood for this self-indulgence. Sometimes you need it.
Amtrak ROCKS. Even when the trains turn into buses at short notice.
London hotels most emphatically DO NOT rock. Similarly priced New York ones do.
And Nancy's right about valet parking. Though after the past 12 months it may be a decade or more before I experience it again
ETA: There are Police fans in the Galapagos Islands.
