Scam at LaBamBam Place

Earlier today I went to this restaurant called LaBamBam palace at Lewanika, The food was good but the waiter and the cashier were crooks... after the food was done I asked him for a takeaway bag... usually most restaurants give that for free... Kanshi this guy charged me a 25, without any shame a 25 for a carrier pack, I was shocked at first then I was like eh I don't want, because I had my own bag,.. then he said ati I punched it already... I was like okey bring me the receipt, at my shock the recipt for the take away bag was ONLY 10 Kwacha... this restaurant is for thiefs .. I demanded the change and he gave me back 15.. but this is very Pathetic... even though the food was good I shall never come to this place again... there are other Nigerian food places in Lusaka.. and most of the reviews on Google Maps for this place is FAKE, how do I know that? Most of the reviewers did only one or 2 reviews, also they were busy praising individual waiters, especially this one called Kelvin... also when ordering food I had asked for one portion of Nshima, and it came with 2 lumps of Nshima, when the bill came Ati EACH LUMP OF NSHIMA IS K30... so 2 lumps of Nshima is 60... I don't know but I feel Scammed. What do you guys think?
