Poor service because I did not buy an expensive pizza!!!

I was at Debonairs Pizza Three Rivers, I received my order 45 minutes later after making a noise because three people that came after me received their orders before me and I am told because they ordered online. Firstly the lady assisting me gave attitude when she saw we had vouchers and told us how small those pizzas are and I asked about the selection of pizzas; she just rep**** chicken and I asked chicken what?? She clearly was in no mood to serve non-paying customers as our pizza boxes we arrived with were chucked to the side and they prepared other important and expensive orders. After placing my order at Debonairs I went on to Steers then Fishaways; I received both my orders from those stores before the "small pizza "and she only took our slips to the back when i started questioning her about the waiting time and that she never explained the was a waiting time longer than usual.
