Being humiliated and disrespected for feeding my child(breastfeeding)

I used to be a big fan of mugg and bean restaurants untill the incident that happened yesterday 2 October 2019. I felt so disappointed, humiliated and disrespected. I was doing shopping with my 2 month old baby in Greenacres mall in PE, then i thought let me have lunch as usual at Mugg and bean. Well the gentle man welcomed then i chose the table i wanted to sit in as i was with the baby pram so i did not want to block the way for other customers and even thier employees when they serving others. I seated the waitress came to take my order, while waiting i got my milk shake then i decided to breast feed my little girl so when the food gets here she's also full and will be able to enjoy my meal. So i breastfeeded her, so another waitress came and say i should cover up and i asked why. She said because that's the restaurant , well i said it's not my 1st time breastfeeding there as i usually do eat there. Then i took the towel and covered my breast and sipping my milkshake, she called the manager the manager said i should cover also the baby with the blanket. I refused told them let me rather leave, because my baby will become restless when she is covered with the blanket it's hot. Mind you the table is close to their kitchen way as i didn't want to block the way. So i said i would like to cancel my order i will finish up the milk shake and pay for it. So the manager said and other 2 waitresses except the one who is serving me standing around the table, i must pay for the food i said no Mem i sorry i won't be able to do that i have not eaten your food. So i told them i leaving i don't feel comfortable and the treatment they giving me is not acceptable. So the they left the table, one waitress did not go as she took the baby blanket trying to cover my baby, i said she must not do that I'm leaving she asked not to leave and not to be upset about the situation. I should understand that there are white customers that have different cultures and they will complain and go on Facebook. I asked her so am i not valuable customer? She did not reply. So the waitress came with the food the i told her i leaving i don't want the food. She came back anf forth packing the food as a take away. I told her i won't pay for the food, she called her Manager again i told the manager again that no i won't pay anf how unhappy i am with the way they treating me. She threatened me to call the security, as i was speaking to them tears were rolling on my face with so much disappointment that about four women standing around me abusing me publicly for just breastfeeding. So i said i will pay to avoid the security being called for me and they should keep their food. Another customer came asked what was the issue as he could see i was un happy and emotional. So He told them they are being unfair as the is no sign or note that breastfeeding is not allowed. So they eventually they gave me my money back then i left.
