Bad bad bad..

Me and my husband went shopping and first we stopped at Mr Price... I saw a special on the little boy pants.. buy two for the price of one.. the pair i took was a grey and cream pants.. when we got at the till to pay the for the items we took I realise the pants that is on special didnt have a price tag on.. the lady immediately assumed I swapped the pants... so my argument today is... if i did swop the pants like she said what does it matter coz al those pants were on special.. FOR the SAME PRICE.. i did not swop the pants but i was handled like a ********.. I left all my items on the counter discussed and left.
