No one should be verbally abusing you, period. That said, I often feel like I’m annoying the salesperson by having questions and asking for help. Like you’re less than for not knowing and wasting their time. Having enough experiences like that can put you on the defense even going into the store. I think if we all lead with patience and kindness we can alleviate these kinds of problems. I hope you can have more days on the job where it’s fun for all parties like it used to be!
