I work in the Deli. There is a coworker who thinks she knows everything and will interrupt you while your dealing with a customer. Lets start with I'll be standing there serving 4 or 5 customers and she'll act like she's too busy to help. I'll then be frying chicken and a customer will walk up. I can't take care of the customer until I have finished dropping the chicken so I'll holler 'Deli please' and by the time I'm done dropping the chicken she'll come to help. I'll then start washing dishes and 1 customer will walk up and she'll take care of them. A second customer will walk and before they even have a chance to look for what they want she hollers 'Deli Please" I'll come out and start helping that customer, then she'll interrupt me while I'm taking care of that customer. I always just walk away, but I so badly want to say something to her. Like "Why did you call for my help if you don't need it?" or "Let me take care of this customer, After all you were in such a rush to get help and now your interfering". She frustrates me to all end and I so badly want to go off on her. I can't though because there are always customers around and I'm on the clock!
