Customer complaints are a "Pity Party"

Cavendish Square Milky Lane - appears to be jointly run by a couple, Mavy and Vish. Initial incident - Ordered the 2 for 1 Tuesday Waffle special (not advertised in-store). Staff member brought the waffles, followed by the tray of sauces to our table. Whilst eating he served another table with their waffles and asked us if we were done with our tray of sauces, took the tray and gave it to the new table. We weren't done with the sauces. We told him this thrice and yet he ignored us. Second incident - When I took the first incident up with the female manager, she handled it in a dismissive, abrupt and disrespectful tone as if to say I should know that they have too many customers to allow each table to keep a tray of sauces indefinitely. While I agree with this in principle, this policy was not communicated to us upfront nor when they staff member took the tray away from us. Why ask if we're done with it in the first place then? Third incident - This brings me to my issue and cause for complaint. I was not happy with the way the tone and bad attitude of the lady manager. I approached the male manager behind the counter to inform him that I will be lodging a formal complaint in this regard. To which the lady manager came charging into the conversation and shouting accusations. The more I tell her I'm not happy with the way she speaks to me as a customer, the more she raises her voice and gets abusing, culminating in her telling me I'm "throwing a pity party", much to the dismay of one of their own staff members. Fourth Incident - After I sat back down to finish my waffle, their own staff member came to apologies to us for the way I was spoken to! The lady manager then noticed the staff member talking to us and shouted across the food court for her to get back to work in a most unprofessional manager. This coming from the same person who told me she can only reprimand her staff (the original staff member I complained about) at the back of the store as the food court is a public place. Whether the customer is right or wrong, they do not deserve to be spoken to like a mother scolding a child.
