My day job is as an IT conusultant. I vape & stealth vape constantly, at my main office, and at my client sites. I have had a few notice the headier flavors I vape, like the black licorice, or clove, but my reaction is always "Hrm, must be my cologne."
I also use a nicostik, and the one time I was caught, I was quickly able to pass it off as "my breathing treatment."
