Had a laugh picturing this. You have to use a call to action to get people to help you get through. Get them to look at you and then look the way you’re going, and start tapping shoulders to help you through. “Coming through” “make a hole” “help me through please.” As you catch people’s attention, nod and gesture to direct their attention forward. It’s like surfing. You’ll catch waves. Helps to be male with a sobering voice I think.
