Being direct often isn’t good enough in the area of customer service. You need to sound pleasant as well.

Be Careful With Your Choice Of Words

“Just see what you want”  may be a casual and friendly way of asking your customer to feel free to browse around.  But it is not Standard English.

The word “See”  just isn’t right in this instance, though it probably came from the local “look see”.

Say “Please feel free to look around”  if you want to sound friendly and make sense to both locals and foreigners.
