Obviously a job in which you deal with the public on a regular basis is the way to go, but some are much better than others. Here are my thoughts on the subject...
I've never been a bartender, but that's gotta be a doozie. I've gotten many terrific sightings in bars, and that's just being a customer. Of course, in our brave new politically-correct world with its smoking bans, bar & restaurant sightings are quickly falling by the wayside. I'm lucky enough to live in an area that still permits smoking in bars (but not restaurants).
Convenience Store Cashier- Been there, done that; thankfully many years ago. Man, what a shitty job. Man, what awesome sightings. My first round was in Panama City Beach, FL, 1987-1988. Highlights- Gorgeous blonde (mid-20s) in business attire bought a pack of VS 100s, got into a white BMW 320i, and lit up before starting the motor & driving away. Gorgeous blonde (late teens-early twenties) in snug summer dress bought two packs of VS 100s & got into a Z28. Gorgeous strawberry blonde (local, early-mid thirties, petite) usually in jeans & a T-shirt bought VS menthols on a very regular basis. Had 2 kids & a station wagon. Preferred Diet Mountain Dew. Buxom brunette (also local, early 30s, always professionally but sexily dressed, favored short, snug skirts, low-cut blouse & short black leather jacket - a very sleek look) bought VS menthols almost daily; sometimes 1 pack, often 2. Drove a plain-jane 4-door sedan that I assumed was a company car. Beautiful customers purchasing Marlboro Reds & Marlboro Lights far too numerous to recall.
Round 2 was in north Alabama, 1991-1992. While not as mind-blowing as my FL gig, the early 90s were still a treasure trove of smoky hotness. There was a very young (16-17) brunette with long curly hair & a truly amazing body who dressed & acted in a manner that suggested that she knew exactly how sexy she was & enjoyed every second of it. She was a daily customer who perpetually needed gasoline, Diet Coke, and Salem Slim Light 100s. I got to see her smoking on many occasions, and she was no beginner or poseur. There was also a stunning late-20s brunette, a schoolteacher, who favored VS Lights. I found out she was a teacher because she had one of those "educator" license plates & I asked her about it. There was, once a week or so, a very hot early-20s party girl who would drop by for some beer, chips, rolling papers & a pack or two of B&H menthols. Again, sales of Marlboro Reds & Marlboro Lights were too numerous to tally.
I may get into my current occupation (multi-family residential maintenance - AKA apartment handyman) in a later post. The pickings out there aren't what they used to be, but there are still jewels to be found underneath the layers of political correctness & self-righteousness that has become mainstream America.
