Weird customers

[nainon]

I have a home business where I sell flowers. It's at rank 7 and I think this weirdness started after rank 3 or so. The problem is that the customers just stand in the street and don't come in. There's usually only 1 sim that comes in and  buys something, and there might come another one after him, but never one of those who just stand there. It's not just this business, it has happened to me earlier on other businesses. I don't know about community lot businesses though, never tried those. And if it helps anything, I only have Pescado's hacks.

Are your customers all broke? That could be why they don't display any interest in looking at anything. Try using the Customer Selector to exclude bums from your customerbase. Business Runs You will also cause sales personnel to automatically attempt to direct loiterers towards something to purchase if no one is buying.

Are you getting any error messages if you run with testingcheats turned on?
Apart from a blocked route the only idea that pops into my mind is Are the doors locked against them?
