Swimming with dolphins part 1

Swimming with Dolphins was on Angela's "Bucket List", and since the prices here started at $A75 compared with more than $A400 at Sea World on the Gold Coast, it was a great opportunity to tick that one off.
We had booked to go on Friday but she came down with a dose of montezuma's revenge on Thursday evening. The company wanted a drs certificate to avoid a cancellation fee, so we went to the doctor's office at the pharmacy and she saw a lovely lady who, after a thorough examination, told her it was something she had eaten (we suspect at the Chichen Itza buffet). The visit cost 35 pesos (less than $3). She was prescribed an antibiotic, some lactobacillus and guava pills to calm the stomach - a good combination of modern and traditional treatments, and the lot cost $20.
By Saturday morning she was feeling back to normal, and we set off from home at 7am for our pickup point at 7.20 (actually we caught a taxi and arrived at 7.07). Another couple was waiting there too.
7.30 came and went, no sign of a bus, then 7.45. We were just thinking of phoning the agency when the bus pulled up at 7.50. The driver looked at the 4 of us and told us there was a problem, because he only had 2 seats left! He checked everyone's vouchers and then got on the phone. From what I could hear, it seemed that extra people had gotten on at the previous stop. I thought he should have asked them to wait for the next bus, but no, he said there was another bus on the way and it would be sorted out then. By this time we were getting thirsty - the sun here is still hot at 8am and we had been promised drinks on the way, and it was important for Angela to keep her fluids up. We asked could we go to the supermarket 1 min away to get some water. No, he said, the bus will be here in 5 mins, better stay here. You can get water at the restaurant on the corner. We did that, paying 25 pesos for a small bottle which would have cost 2 in the supermarket, and the bus took at least 10 minutes.
But it was when it arrived that we were surprised. Instead of herding us onto the buses, the drivers removed 2 seats from the back of the new bus and inserted them into the old bus. The other bus took off and finally we were on our way at 8.15 - I was very conscious that I would have enjoyed that extra hour in my bed instead of waiting in the sun, but at least all would be fine now.
