Poll is missing an option.
"Same" should be included. As a bar owner I am unable to see any difference in ordering by me not drinking anymore.
Not to mention sales reps have quotas where their boss is on them to have sit down sales sessions with as many of their customers as possible.
They love the reliable sources which mean they always pack special bottles when they come with samples. I've sipped a shot of tequila that was poured from a bottle with a $1900 wholesale price tag.
If they know you'll sit down and drink with them for an hour they'll be at your place a couple times a week. They have GPS devices and are monitored. I'd spend my afternoons tending a slowish lunch place with a revolving door of reps bringing me free drinks.
That said I'm taking more ownership in my place and labor was down a considerable amount last month so I suppose I might just need to look at the big picture.
