Mayer was minutes into an on-stage conversation with Salesforce.com CEO
They were protesting worker conditions at
The protest lasted about a minute before protesters were escorted out of the Moscone Centre. They were heard arguing loudly with Salesforce staff outside of the conference hall shortly afterwards.
Marissa Mayer is a director of Walmart, and she said on stage that's what she thought the protest was about. Walmart has made headlines in recent months for reportedly paying nearly two-thirds of its workers less than $25,000 a year.
One Walmart store in Ohio is reportedly holding a charity drive for staff who are otherwise unable to afford enough food for Thanksgiving.
But Benioff and Mayer had the last laugh after the protesters were removed. The two were talking about the importance of product design when they were interrupted.
Benioff is famous for disruptive gorilla marketing at competitor's conferences during Salesforce.com's early days, and couldn't help himself but to comment:
"We don't want any more protests ... but if you want to protest, No. 1, you can do it outside. No. 2, it's better to spit up when you start. Then when those people get arrested, then a second group stands up. Then a third ... I'm just saying"
The audience laughed and Mayer said, "That's a design problem right there."
