Believe it or not, some people (including the person behind the counter at the cigar shop) have a difficult time cutting the cigar tip. Most of the time I have found that the shop is just trying to do you a favor in offering to cut the cigar for you. However, you should use caution; a v-cutter, straight cut, or plug cut, can be screwed up by them just as easily as it can be by a novice cutter. Don't think they mean any harm by it, just an offer to help (BTW if they screw it up (the cut) you can always ask for another cigar).
