It is important to remember that directly or indirectly we are the face of bodybuilding. I take a min between sets to offer advice, I will not let small talk or long talk effect my routine. My routines are made to last an hour and I stick to that.
I remember being 16,17,18yo and not knowing much in the gym... Not knowing diet, not knowing form, and when I was 18 a guy took me under his wing and taught me.... Since then I have taught myself much but there are still times I am at the gym and I ask others questions and seek advice.
Yes, trainers charge $50+ per hour to give advice, but look at 90% of the trainers... I wouldnt even seek free advice from them.
We need to help improve the body building image. SO many times I hear the negative ways we are preceived, and I dont like that. Our community is represented by strong willed, determined individuals with a common purpose of improving our lives and that is what should stand out when we are preceived.
Bottom line is take it as a compliment when someone approaches you, and take a second and offer them some advice, it not only builds your character but the character of the sport.
