Was this woman being serious?

I got a call from my mum today while I was at the city with my friends and she asked to me inquire about the watch that she wanted at this specific jewelry store. I knew what the watch looked like because my mum pointed it out before in the sale catalogue. I was looking at the ladies watches to find the watch that my mum wanted and as usual the saleswoman asked me if I needed any assistance. I replied no thank you and that I was just looking around. But she wouldn't leave me alone, she kept standing and there and asking me if I was purchasing a watch for my boyfriend (*sarcasm*yes because I would totally purchase a lady's watch for my non existent boyfriend). Before I had time to answer my friends thought it'd be amusing to shout 'YES." The saleswoman seemed surprise and she kept asking me if he was rich and handsome. She kept going off rather unprofessionally about my how supposedly lucky my non existent boyfriend was. At this point I was extremely embarrassed and very uncomfortable, but my *wonderful* peers decided to take advantage of the awkward moment and hint that my non existent boyfriend was an unemployed nobody. The saleswoman continued to patronize me saying that he probably had a secret hidden stash of money at home hidden from me and that he was a drug dealer. At this point nobody laughed not even my friends because I just stood there stunned. She walked away and I immediately left the store. I probably over reacted but the woman's intentions were to humiliate me which was a shame because I didn't tell my mum about that specific store and found another one with a better price on the watch. I guess my question is have you had a similar experience to mine?
