The Imam tells the story of once he was dropping off his family at the hospital and a brother that they know well walked past. There were people around and the brother walked with his walking stick. The Imam tried to catch his eyes to give him salam but the Brother saw him, and ignored him! 

Why don’t we give salaam? In society they know you are a Muslim so there is no need to be too embarrassed to give salaam. Allah has given us  the greatest blessing, if we die with emaan our destination is jannah. People in the street don’t know who you are, if they know you are a Muslim so what?

May Allah save us and making us such that he is pleased with us. Ameen.
