Poor poor customer service

I went to Krispy Kreme at Middelburg mall at around 16:45 and the staff were already packing away the donuts I had to wait for my brother to bring the money I would be paying with. When he arrived it was about 17:15 and there were only 2 flavours of donuts I asked whether this was all and they said yes but I had previously seen them pack them away they have an attitude as if they were doing me a favour. Later when I would pass by the stall they would point at me and snicker amongst themselves. Because I am a teenager they gave me bad service as if they were doing me a favour .
