Bad attertude and behaviour

So today I visited the Pick n Pay in Mitchells plain Promenade, and as I approached the cashier herseld,the packer and another packer nxt to there till was having a conversation..for a sec the cashier noticed me and scannend my things however the conversation kept going,the oppersit packer felt the need to use voul lang and ignore the fact that I was standing there...as my husband came over they stopped talking luked him in the face and started laughing out loud, we both looked at one another and ognored the confrontation. As we walked away they continue the laugh as I turn around they keep staring and laughing...ita not the 1st time that Iv experiance such horrible service....the youngsters has no ethics...they dont know about greatimg or being polite...the elderly people are more respectful than that bunch of young bunch...I felt so uncomfortable and annoyed by there behaviour..I would not recommend that store even if its the last store open...their customer service will never level up to a woolworths.staff as no respect
