Where did all the customers go on Zynga’s Cafe World?

As of yesterday, November 14, customers have disappeared! The streets are empty and at most I have three customers in my cafe at any one time even though I have 17 tables, 7 counters, and 6 waiters. Up until yesterday, I had a consistently full cafe and a buzz rating of 105.0 whereas now it never goes above 5.4 since there is hardly anyone walking the streets of Cafe World.

Is it the recession? Did someone get food poisoning at my cafe and tell the world about it?

Anyone else having this issue or know why suddenly the streets are devoid of people?
