Possession in Akshayanagara West, yaar, hidden costs surprised me

Possession for my flat in Akshayanagara West was in March, and honestly, the all-in cost surprised me. Ambika Developers had so many last-minute charges – club house, utility setup, maintenance advance. Mera budget 8% tak badh gaya. Negotiation pe they barely moved, maybe 10-15k max. Did anyone actually manage to negotiate better on these hidden charges during possession? Or is it just standard practice in Bengaluru for builders to add these later? Curious to know others' experiences.
