Varanasi is famous for its thug also, on my personal experience, vendors are very clever, 1st they told you correct price and when you give them money they refused for eg mene vaha juice pia aur glass rakhne laga to ekdum aur daal diya aur kaha pio pio utna hi pesa lagega, aur jb 20 rs dene laga to khte 40 hue, 2glass k, mene kha ki apne hi to kaha utne ka hi h to khte utne ka hi to h, tbi 40 hue, same aesa fruits bechne waale k saath hua.
