I tend to refill my bottled water in the parks instead of buying a new one, but to cover the FL water taste I use flavor drops or powder packs. Well, I don't use the iced tea flavor anymore.............I was stopped park hopping to HS a while back, bag checker though it was booze in a Dasani bottle. I was mortified, never thought little old me would be stopped for smuggling liquor! I just wasn't thinking of anything close to that. Security checker did believe me that is was iced tea after a sniff test, but nicely warned that in the future might want a different flavor for my water if I didn't want to repeat that scenario. Was all done calmly and respectfully, and I do understand that they have to check so many people so quickly to keep the lines moving that anyone in doubt would be stopped, just wasn't thinking that iced tea not in an iced tea bottle would trigger anything.
