LIS - MIA

I don't understand why an aircraft that arrived in Lisbon at 5;19am for a 10:35 flight was immediately delayed until 11am , then 11:17 am. Also, after being on the plane and taxiing for an hour, they discovered a computer error and we had to change planes. All in all we had a 5 1/2 hour delay. The boarding process for the second plane was chaos. They herded everyone out of the boarding area behind ropes, and then didn't announce anything over the loud speaker, but had a single agent yelling Premium only. Needless to say, there was pushing, yelling and confusion. On board, I have never experienced such a lazy, lethargic crew. We were in business class. We were not offered a drink or the usual bowl of nuts. We were given lunch about an hour into the trip. the food was mediocre at best. My friend, who had preordered the pasta dish over a week ago, was told that they were out of it and she could only have octopus, which she does not eat. Meanwhile, she saw 3 other passengers get pasta that they had not preordered. Shouldn't the pre orders be given priority? For the next 6 hours, we did not see a flight attendant, until they announced that they would not be serving another meal because they were "overworked". (same crew that was on the first aborted flight). Fortunately, I had to use the restroom and noticed a basket with sandwiches and some cookies. I asked the flight attendant if I could have one, and she said "of course, these are for you". Nobody let anybody know that there was food available., and no one was offered any drinks for 6 hours. I had to get up and ask for a bottle of water. Finally, they never came around to collect trash, so I left my trash at my seat. I will do everything in my power to not have to fly TAP again. Also, I think there is a law in Europe that passengers delayed more than 3 hours are entitled to some form of compensation. I will pursue this.
