What does "perception" mean here ?
I think that it is important for business partners to get familiar with each other first and to feel relaxed. If the exchange is too abrupt, there is a risk that something will be forgotten. Some possibilities go without being assessed when there is too much pressure. I don't believe this is the best strategy for proper communiation. Besides, the perception is that they just don't care about you as an individual here. You are basically just another means of making money.
