when i get bad customers that haggle with me(over $1 lol) i say i cant do that, bottom line. no explanation or excuses needed. it's just 'i can't do that'. if they get pissy, i politely ask them to leave. if they refuse, the cops are on the way. no threats or rude language, shouting, or camera slap shutting off-ing needed. nowhere should you get physically involved.
there is a right way and a wrong way to handle customers, no matter who is at fault. and that was not apparent in this video. hence, i will no longer go there.
