It really depends on what kind of diaper I am wearing at the time, and even if I am using a nice thick pad as well at the same time. If I am just wearing my Silhouette diaper pantie only then I am aware of how much I can wet while dealing with whatever in the store, but if I have a pad inside then I know I can wet with a bit more freedom. Sometimes I will just wear one of my lovely panties with a pad inside so that I can wet in little trickles as I go about my business.
