Disgusting behaviour at checkout

At checkout... chatting constantly to packer who is parking off on a chair, really laid back job. Asked me "you want plastic?" To which i rep**** to the affirmative. After the laid back one on the chair had squeezed all she could into one bag, I had to carry the remainder of my purchase seperately, juggling it all as I did... not sure if there's a one per customer maximum on packets... but please.... use your flippin brain, I have to carry this stuff. On top of this... cashier insists on taking card from me for payment, fortunately I am not a complete idiot and know how this fancy card machine works....and due to the lack of honesty in this country, I am hard pressed to hand my card over... so don't take my card and violently shove it in the machine (which damages it)... then ask me cheque or savings, because when I say neither, you'll have to figure it out... you've taken it... you must know all the answers. P.s. I can remove it from the machine myself as well. And when I walk away... juggling my loose items that I'm not allowed another bag for... what do I get "oooh uhuh" from behind me.... my initial instinct is to turn around and slap these rude arrogant individuals.... but that would make me wrong, wouldn't it. Builders.... you have dozens of staff standing around your store doing stuff all. Many of your products are not priced/correctly marked. Majority of your staff appear to be doing everyone a favour by being there... not me I'm afraid. I'll just shop elsewhere. Shocking.
