Not much compares to what I make at home or at the shop, but I have a rule: no more than 30 seconds should elapse between the time the beans are ground and the hot water hits 'em. Also, I make it very strong, because that's what makes it smooth.
On the road, it's hard to beat Starbucks. I don't care if they are a bunch of Seattle Snowflake outposts, they know what they're doing when it comes to coffee. If someone doesn't like their coffee, they don't like coffee. Tim Hortons or Dunkin Donuts I can handle. A lot of the convenience stores now have the coffee makers with the built in grinder so you can get a pretty decent cup of fresh ground coffee.
