How do you say:"You(formal) were yelled at by a salesclerk in a store yesterday?"
I have to use the words: ustedes, fueron, dependiente en una tienda and anteayer.
Ustedes is you all, not formal, and anteayer is the day before yesterday. Therefore, I'm not sure what words to use.
¿A ustedes les gritó el dependiente (o empleado) de una tienda ayer?
fueron is not possible here, and neither is anteayer, since yesterday means ayer
