What should I do if my pension is credited late due to weekends or holidays as I apply for an extension of stay in Thailand?

There is no short way to explain this! I'm just putting together everything I need for my extension of stay application(over 50 based on retirement). I have left plenty of time to cater for any problems. In the past I have had proofs of income certified by the British Consulate but of course this time I'm getting my SCB to provide a single page letter showing monthly income by International Fund Transfer from my pension provider(the UK govt) to the SCB. I easily exceed the minimum required amount of baht 65k a month. So far so good and the SCB are on side after a very long discussion!. BUT my income reaches my bank on the 30th of the month. The only snag is when the 30th falls on a bank holiday/weekend when the main bank is closed for whatever reason. That means it is credited on the 1st or 2nd of the following month. For example 30 Mar this year was a Sat therefore my income was credited on Mon 1 Apr( actually my March pension). The next credit was 30 Apr - two credits of income in the same month.This has happened 5 times over the last 12 months. Has anyone else experienced this problem and is immigration relaxed about it - the Jomtien/Pattaya one that is?
