Don’t dine alfresco. Men keep your back to the wall. Most women are next to useless, in watching what’s going on, for awareness of shit about to go down. They aren’t much use if the assailants are men(even soyboys) when you are outnumbered. Most people, men and women will be intimidated by the threat of violence in a so called civilized part of town so don’t expect any help.
You’ve got access to blunt metal cutlery, glasses, and chairs. You can fuck someone up badly if you absolutely need to with this gear, and they don’t have firearms. A preemptive strike and then get the fuck out is your best option. Once a mob gets worked up to violence its too late, you are at their mercy unless you are armed.
There is usually a “mouth”, who starts all the trouble, maybe a vocal woman, with BLM. They might be willing to enforce, but more likely there will be 2 or 3 “enforcers” close by, trying to outflank you, when the mouth has your attention, ready to take action whilst you are distracted. Target your attention on the enforcers, deal with them and the others are more likely to disperse out of fear for their own skin.
Really its the restaurant’s job for security, but nothings going to get done unless its the local Mafia’s Italian eatery, or perhaps a Triad owned Chinese restaurant.
All the Police will do is arrest you for affray, or worse. They will scrape your remains up off the pavement, after the mob has left the area.
In this climate you are better off staying away from these areas, and avoiding the trouble in the first place. These are troubled times indeed.
BLM mobs and antifa are evil scum cunt violent criminals.
