For future reference.
When you are walking along with your bag over your shoulder it is most likely that the bag will protrude slightly from your body. Please be aware of this fact, particularly if you are walking down a narrow(ish) pathway which has room for two people to pass, side by side.
This is a friendly reminder is so that, the next time a bag clouts me in the arm, leg or side, I won’t have to fight the urge to throw the bag into the River Clyde. Possibly with you still attached.
That is all.
