You seem to be getting very excited about this thread, Brietta. I say again, instead of complaining why don't you set up a thread discussing the matters you are concerned about? It does involve digging about in the files to get the information but I'm sure that won't be a problem for you. You might find a remark by a waiter about someone who was concentrating on writing in their notebook labelled 'Movements of the naive twerps who have told the receptionist and other holidaymakers that their cute little kids are being left home alone every evening'
Approaching this from a somewhat different angle, doesn't it intrigue you what the other diners in the Tapas restaurant saw from Sun-Thu that week?
The Tapas restaurant is not large and 9 diners (barring illness) sitting at a single big round table (BRT) should have stuck out like a sore thumb.
Waiters, IMO, would have noticed only a little as they served.
Bar staff, IMO, would have noticed next to nothing, at least until the T9 decided to move from wine to a nightcap.
That leaves other diners as the best independent witnesses to the checking routine. Was the T9 quiet or animated? Were people frequently leaving the restaurant, for whatever reason?
My last 2 meals out in Luz have basically been trashed by a lot of noise generated by others. Both times I was trying to have a quiet, discreet discussion of aspects of the case. In the first instance, we picked a quiet table and everything went well, until a party of 6 arrived and chose a table quite near us. There was one woman who thought the only way to talk was at least at 80dB, and quite soon her party of 6 were all shouting. Then the other diners found that the only way they could make themselves heard was to shout louder than the party of 6, and the restaurant turned into a battle of who could talk the loudest. In the second instance, the restaurant owners had a young boy of about 3 who was running around playing, shouting as he went. No quiet conversation there either.
There is a list of people who, potentially, can provide evidence on the checking routine of the Tapas 9. That list is those diners occupying the Tapas restaurant at the same time as the T9.
Did the PJ check this in Amaral or Rebelo's time? I can't see anything to support this.
Did any of the McCann PIs check this? Presumably not, this would be outside their remit.
Did OG check this? Presumably not, given the OG remit.
Will another McCann team check this? I'm guessing not, again based on a remit idea.
But all of this lot should/should have check(ed) this, because it imposes restrictions on an abduction or alternative theories.
The folks who can provide independent verification of what was happening during the Tapas meals are the other diners.
