I think that the type of Russian tourist has changed over the years.
A few years ago, it was the obviously sucessful businessmen, accompanied by much younger, very attractive, usually scantily clad regardless of location 'partners'.
Then we noticed younger couples, with money to spend.
This year, there seemed to be quite a lot of families with children and groups of girls/women (didn't notice groups of blokes though that's not to say there weren't any).
They were eating fruit & sandwiches on the beach, obviously brought from their hotel/apartment and also drinking stuff they'd not bought in the shacks.
Maybe the cost of getting to Goa for these people is stretching their budget so they don't have a lot to spend when they arrive there.
We saw 2 women in a bar in Calangute spend 10 minutes studying the menu before ordering a small bottle of Bud between them - nothing else.
I heard two chaps asking the price of a gin & tonic in a beach shack and discussing what they were told before they finally sat down and ordered.
I overheard a guy arguing with 2 of the beach shack guys over what he'd been charged for a soft drink.
Apparently, the shack has done a couple of menus in Russian and one of the prices had been put in incorrectly (5 rupees less than on the English menu).
This guy was insisting that he'd ordered from the Russian menu and would only pay Russian prices.
I don't know the outcome of this as I got bored after 15 minutes of stand-off and wandered down the beach for a paddle.
I don't know if this means they have limited budgets or it's just part of their nature/culture.
Regarding Fritz's comments about the feeings of the Goans towards the Russians, I know the jeweller that I use is often uncomfortable about the way they behave in his shop.
He says that English people come in, say 'Hello' and if they see something on display that they want to look at, they will ask to see it.
Russians come in (quite often in large groups), don't speak and start picking things up and trying them on, which makes it very difficult to keep track of stock.
I was in a handbag cum jeweller shop a few weeks ago that I have bought from over the years and had just spent a while haggling good-naturedly over a Jimmy Choo handbag, me declaring that I just couldn't possibly afford to pay the extra 50 rps that he wanted and him saying that if he sold the bag to me at such a low price he'd go bankrupt. Anyway, I was paying (the lower price)

and someone came into the shop and the guy said 'Russians' and made a sign that he needed to keep his eyes open.
