Bringing hot sauce/condiments when eating out

Got my keygoes:chili keychain in the mail today. It's a cool little product. Good quality. The logo is engraved into the metal (which is good since your keys are going to be banging around on it) and it has a cutout on the side to see how much powder is left in the vial. The top screws on and the cap has a silicone "plug" in it to keep it sealed. It LOOKS like the vial of powder can be reopened to refill it but the idea is to buy new refills when needed which I don't think I'll do since I have plenty of powder around the house. They also sell empty vials online. I chose the bhut jolokia powder but there are other powders available. All in all I'm pretty dang happy with it. $15 plus shipping on amazon.
