Fastrack — Bad behaviour towards customers from employee

Address:

fast track,lakshmipuram ,guntur ,beside kfc.

It happened in guntur, lakshmipuram fast track store,
one of the employee insulted us among other people
asked us to leave shoes and slippers outside while all other are wearing shoes and slippers inside it made us feel bad, i didn't expect this kind of gesture from fast track, it is humiliating to go back from store with buying any thing because we wear shoes and slippers later we went to other store for watches all them welcomed i got watch out their.i don't understand what is the problem of that employee if we were shoes or cheppal
i want explanation regarding this behaviour or else i will share this experience with people in social media, i felt very humiliated
