Little bit of work rant 😤😡

I’ve had this job for about a months now. And the boss has the habit of changing prices of items almost every day ( including putting discounts) and she doesn’t let most of us know. Not by the Whatssapp group chat or when we get there. So today I found my self asking her prices of items that didn’t even have tags on them. And she just put me on the spot while I was with a client. Like what am I supposed to do? Just guess the price of the damn item for that day 😤 I always find my self asking her and some of my co workers who have been there longer because I honestly have had situations where I tell the client a price it had a day or days prior just to have one of them tell me the cost has been lowered or it has a discount. If that’s so that PUT A F PRICE TAG ON IT.
