Monday, during lunch hour: Man comes into Advance Auto. I am already there, in the back, looking at oil prices. Salesman asks him, "may I help you?" Man quickly and gruffly replies, "No, I know what I'm looking for and where it ought to be." I hear his foot steps quickly approaching me. I nearly out of time anyway, so I begin to slowly head out of the oil section. I pause, pretending to look at the grease, but really I am curious about just 'what' is supposed to be 'where'. The man quickly scans a diesel-type display island with Delo and such- the 15W40s. The man throws his arms up and pivots quickly to place is gaze squarely at the Castrol Section in the main oil shelves (GTX is on sale for $1.77, no rebate required). He looks directly towards every offering, individually, studying them each, and then shuffles to the left. He's in the Valvoline section now, nothing special going one there, and his effort seems to be reduced. He continues to the left at a stroll. By the time he gets to the Mobil section, the oil seems to be calming him. I circle around through a row full of crap, shining things that don't serve a purpose. Chrome tire valves or some-such. I don't let them distract me. I approach from his blind side and begin competing for shelf space like just another shopper on an oil mission. He leap-frogs around me which places him near the end of the oil section - the Shell section ($1.24 but you have to buy in multiples of 12). He figits with one of the bottles to get a better view. He needs to move some of that "between the shelf crap". You know some sort of bending funnel, or 3-packs of rags, or something. The calm is abruptly shattered as he spouts "I knew I wouldn't be able to find this she'it anywhere" (I'm in the south, fecal material is pronounced with two syllables here - shee-it). Since it is clear that he wants something that belongs in the oil section I slide into his flight path to slow him down. When he looks up, I look directly into his eyes and ask with curious disgust, "so what have they quit carrying now?" I thought I would allow him to be the provider of info.. some sort of authority position in the interchange. He looks at me as though he had an unsolvable question but then began to explain with animated disgust and clinching teeth, "I just let my daughter talk me into get'n one of those foreign Accord things and it needs 5W20. Who has ever heard of 5W20. Where am I supposed to get may hands on some crazy Japanese oil." He continues to rant about 20 weights and american cars, and the way things use to be, and something about a sewing machine or sewing machine oil or something. Since we were still positioned in front of the oil, Havoline even, I reach around from memory, without looking, and grab a bottle of 5W20. I display it like wine across my arm. "Here's some" I interject. "It's pretty good stuff too." I had to look this time, but I found a bottle of Motorcraft 5W20 and while pointing at it I added "a lot of the Ford's are using it these days" I went down the row and pointed at essentially the first offering of nearly every brand. While I was overdoing it, he added "yea...but I bet Mobil does make stuff this watery." I had skipped the Mobil because it started on the bottom row and my arthritis doesn't appreciated unnecessary bending. But, since he asked, I pointed with my toe, "sure they do..and in a few more years you probably won't be able to get anything heavier." I had quenched my curiousity, helped a guy, and was a little late. I walked out of the store. And that .. that guy .. and forested acres of guys just like him, is why I really thought that the GC around here might last forever.
