Shopping is a social skill

To-day, I bought a BMX bike for my son - think of it as an early Christmas present. I wonder if my poor conversational skills (possibly Asperger related) affect my shopping. On this occasion we entered the shop, within a minute had seen the bike we wanted, and within 10 minutes were leaving the shop with the bike in our possession. I suspect that someone more adept would have taken longer, but in the course of doing so would have said and heard things that would have made buyer and seller happier with the process. I have always known, I guess, that I would be a useless haggler. But I'm happy - it's a gorgeous bicycle.
