Salami Slicing
In a transactional context, sometimes your counterparty may try to essentially scam you for a small margin -- so thin that they hope you do not notice, or let it slide because it basically doesn't matter. By doing this over and over again, your counterparty hopes to accumulate some meaningful aggregate advantage.
This is an amateur technique, because Salami Slicers usually do not realize that:
1. People notice. They may not say anything. But oh man do they notice.
2. Being recognized as a Salami Slicer is extremely negative and will kill you in social and business contexts, because you are showing that you will compromise your ethics for trivial amounts of money (or whatever else is at stake). Nobody will trust you for anything significant if they know you're the type of degenerate to steal pennies while others aren't looking.
In fact, frequently, people will permit others to Salami Slice them as a kind of test -- will you do the wrong thing, thinking you can get away with it, for a small amount? A valuable signal. Thank you.
Skilled Salami Slicers will maintain some level of plausible deniability -- "I'm sorry, I forgot to keep this minor obligation", "oh I wasn't sure whether you were paying this or I was", "I thought I didn't have to do this thing because of that other thing", etc. But there are patterns to this, and you can sniff it out quickly. (For example, Uber's ETAs are always optimistic -- the cars are always late or on time, but never early. Huh.)
Some people will go 0-to-100 when they notice they're being Salami Sliced, because they understand what it says about their counterparty's view of themselves: it's extremely dehumanizing. If you try to strategically and deliberately deceive me for minuscule gains, then clearly your view of me is so low that you would cause me unlimited suffering if it was to your benefit. In a Schmittian sense, it's a hardcore Friend-Enemy distinction. Amateur Salami Slicers are occasionally surprised when they are spotted and receive the full Fuck You I'll Kill You, scorched-earth zero-mercy response: their counterparty understands the full symbolic reality of Salami Slicing.
I hate being Salami Sliced.
Standard experience booking an Uber
“5 minutes away”
I order it
“Finding your driver…”
“Pickup in 7 minutes”
I open my timer
9 minutes and 21 seconds later, it arrives
This is so tedious and I am tired of being deceived at the margin
