ugh i feel the same way.
i went to
best buy about a month ago to look at a few tablets and as soon as i walked over to them a salesperson walked up and asked if i needed help.
i said i was just looking and i'd let him know if i had a question.
he walked away and within 30 seconds another person walked up and asked if i needed help. i politely said i was just looking.
no more than a mintue later ANOTHER person walked up and asked if i needed help. i said "no but if i do you'd be the 3rd person in line for me to ask a question to".
then one more person walked up and asked if i needed help.
i said "seriously i can see you all standing around 20 feet away from me and you don't think that i'm aware that as soon as one of you walks away the next person from the group standing over there comes up to me? is this some kind of game? are you really that bored? now i'm not buying a tablet from here so none of you get a sale." and i walked right out and went elsewhere.
