Extremely poor and bossy service from Engen petroleum

I normally use engen and appreciate and respect petrol tenders, today I decide not to use the one near by due time, on my mind I was telling my self that after dropping my kids i use the one near their school , when i arrived i waited like 5 mins i hooted one of them attended i greeted he keeps quite his not even covered him self with a face must properly , i give him my money an tell him may I please have 95, he pulls his face Rudely and not even asking me propaly he clap his hands and tell me move move and make it fast go to that side for 95 am so annoyed by his face attitude and clapping hand like am a child i still calm my self and ask him not to talk to me like that in a calm way he them through me with my money on my face and told me to go or I should ask someone to assist me , am not sure the treatment that i got was it because am a lady or its an on go ing thing , I was so discarsted after a poor service and bad treatment am suggesting they should be trained proparly
