Pathetic staff attitude

Wow, I never thought I would start the year like these, after meeting one very friendly lady in another aisle at the store, to the Pharmacist Elizna who is always friendly and helpful to a cashier who had attitude because I was distracting her gossip with her colleague next to her till. She just kept giving me unnecessary attitude. I greeted her she doesn't respond because she's busy with her colleague talking, to talking about me with her supervisor as if I'm not there, simple thing I'm redeeming the voucher and I disclose it's a ucount voucher but she still asks is it Vodacom which proves that she is not present she is elsewhere. To her calling her supervisor ' come she has added something else' and again come and void she has decided to add again. It's too early for such an attitude. I would probably have understood if it was late afternoon and assumed that she had a long tiresome day but not in the morning. If she's tired she's must stay home.
