Removing cached reference to missing table: services_user?
That table was added in Services 7.x-3.10; it sounds like one of three things has happened:


You've updated the module but not run the database updates. If you have drush run drush updb, or visit /update.php to go through the process.
You've already run the updates but something went wrong
The table was removed accidentally (maybe by a backup restore)


In either of the last two cases, you can install the table manually with:

$schema = drupal_get_schema_unprocessed('services');         
db_create_table('services_user', $schema['services_user']);


or

module_load_include('install', 'services');
services_update_7402();
