in your general assortment of items to carry about with you while riding keep a tube repair kit like the 'Park Tools Tire and Tube repair kit (TR-1)'. Comes with adhesive backed patches, a small square of emory cloth to scuff up the area to be patched and tire levers. Very small kit, very important kit and will save you from walking her back more than a few times. As small a pump as you can get away with, minipumps are not as good as a good old fashioned full sized t-handled pump (get one of those for home, I have one at home and keep another in the trunk of my car) but a minipump is generally small enough to toss in your pack and will ensure that you have a pump handy when needed. Works well, but tend to give you a bit of a workout BUT when needed and you our out in the wilderness it is a godsend.
Flats happen! For some folks more frequently than others. Unless the tube was not installed properly (pinch flat because of tube not seated properly) I fail to see how this is your shops fault.
Some folks carry an extra tire in their backpacks (catastrophic tire damage is rare but does happen...sharp rock rips your sidewall for example), depending on the type of bike/riding you do it might make sense to toss a folding bead tire in your pack (only if it makes sense for your situation of course.). Consider also a spare tube. Of course the other obvious avenue would be to seek out tires that are better at resisting punctures, thicker tubes (thorn-resistanct for example) and/or "slime" to assist in managing punctures. All a balance act and simply depends of how much redundancy makes sense for your situation...The ultimate I suppose will be to go 'tubeless' and use stans no-tube solution. Lots of mountainbikers do this and swear by it. It will likely mean you have to first find the tire/wheel combination that is ideal. Check out vid! http://youtu.be/FTlZvOVG8zs
. Going with a 'Stans' solution pretty much means no flats ever again (tears could happen tho) and generally is the 'ultimate' solution out there.
I dont think the loose presta valve nut would cause it unless you had sharp edges or burrs on the stem hole of your wheel. Is that where the puncture occured? If so it would obviously be the cause and I would then talk nicely with the folks at your LBS.
Either way, when repairing a flat be sure to run you hand around the entire inner circumference of the tire to make sure you locate and account for whatever caused the puncture. If not you might find yourself repairing a puncture only to mount the tube and subject it the the very same object (thorn head that pierced thru the sidewall for example) that caused the puncture. Feel about and look to ensure there is nothing in there to cause any bother.
Always carry a repair kit and a pump of some sort, debris and object sharp enough to cause bother are an unfortunate fact while riding on the trails and it sucks to be miles along only to have some otherwise easy to repair flat force to you to have to walk all the way back to the trailhead/car..total pain.
Once you know how, repairing a standard flat wont take but three or four minutes, often a tad faster if you quit screwing around and take the wheel off the bike (I have to tell myself this at times...always goes faster if I just take the darn wheel off).
