I agree with all the posts, but feel that maybe they can be a bit...I wouldn't say 'agressive,' but I would say maybe 'bold.'
Last summer, while at the Marriott on STT, while in the Morningstar pool, my family and I watched these three elderly women come in to the pool area with lunch they had apparently just purchased at Coco Joe's. The one woman sat down at the table, and placed her lunch in front of her. The other two women were chatting and facing the opposite direction. We watched as a large iguana climbed up the back of her chair, and went to reach across shoulder, to get to the table for her lunch. When she saw this iguana, about 2 inches from her face now, the woman let out an extremely loud scream of "Get Him Off of Me!!!!" The other two women then turned around, and one of the whacked the iguana extremely hard sending it flying to the ground. The woman was not hurt; the iguana, however, I am sure, was never quite the same after that.
It was one of those situations you want to react to help, to warn her that this iguana was very quietly and sneakily climbing up the back of her chair, but we didn't have time. I must admit we did all laugh and quite loudly at the scene, which then caused the three elderly women to turn around and start yelling very loudly at us. My brother (65 years old) tried to apologize and explain that it we didn't mean any harm...we simply couldn't help but laugh.
Anyway the three women then left, and we did not see them again at the pool for the remainder of the week. To be honest, we laugh about that to this day. Insensitive, I know. My husband is totally spider-phobic...I laugh at him also, as he does at me for those things I fear, mostly without much reason....
